Keyword: [Errno 14] problem making SSL connection
Summary: This article provides a comprehensive overview of the “[Errno 14] problem making SSL connection” error. We delve into the root causes, ranging from simple network configuration issues to more complex problems related to certificates, firewalls, and server-side configurations. The article offers practical troubleshooting steps, emphasizing the importance of systematic diagnosis and leveraging system logs for effective resolution. Various scenarios are explored, providing readers with a solid understanding of this common SSL/TLS connection error and equipping them with the skills to effectively resolve it.
Understanding the “[Errno 14] Problem Making SSL Connection” Error
The error message "[Errno 14] problem making SSL connection" typically indicates a broken pipe or a problem with the underlying network connection during the SSL/TLS handshake. Errno 14, or `EPIPE` in POSIX systems, signifies that the connection has been unexpectedly closed by the remote host. While this often appears related to SSL/TLS, the root cause often lies before the encryption process begins. Therefore, troubleshooting needs to be methodical and consider several layers of the networking stack.
This error can manifest in various contexts, including:
Client-side applications: Web browsers, email clients, and other applications that use HTTPS.
Server-side applications: Web servers, mail servers, and other applications that accept SSL/TLS connections.
Programming languages: Python, Java, Node.js, and other languages using SSL/TLS libraries may throw this error.
Common Causes of the “[Errno 14] Problem Making SSL Connection” Error
1. Network Connectivity Issues: This is often the most overlooked cause. A transient network problem, such as a temporary loss of connectivity, a faulty network cable, or a router issue, can lead to the abrupt closure of the connection. Even if the connection initially appears to be working, a brief interruption during the SSL/TLS handshake can trigger the `EPIPE` error.
2. Firewall or Proxy Issues: Firewalls and proxy servers can block or interfere with SSL/TLS connections. Ensure that the ports used for SSL/TLS (typically port 443) are open and properly configured. Incorrectly configured proxy settings can also disrupt the handshake process, leading to the “[Errno 14] problem making SSL connection” error.
3. Certificate Problems: Incorrectly configured or expired SSL/TLS certificates on the server-side can cause connection failures. Self-signed certificates, if not properly trusted by the client, may also lead to this error. Missing intermediate certificates in the server's certificate chain can also disrupt the validation process.
4. Server-Side Issues: Problems on the server itself, such as resource exhaustion, application errors, or improper server configuration, can lead to premature closure of the connection before the SSL handshake completes. Server-side logs are crucial for investigating this aspect.
5. Client-Side Issues: Similarly, issues on the client-side, such as incorrect system time, corrupted SSL libraries, or resource limitations, can also cause the error.
6. DNS Resolution Problems: If the client cannot properly resolve the hostname to the server's IP address, the connection attempt may fail, resulting in an “[Errno 14] problem making SSL connection” error.
7. Load Balancing Issues: In environments with load balancers, misconfigurations or issues with the load balancer itself can cause intermittent connection failures.
Troubleshooting the “[Errno 14] Problem Making SSL Connection” Error: A Step-by-Step Approach
1. Verify Network Connectivity: The most basic step is to ensure a stable network connection. Ping the server's IP address and try accessing other websites to rule out broader network problems.
2. Check Firewall and Proxy Settings: Review your firewall rules and proxy settings to ensure that they allow outbound connections on port 443. Temporarily disable the firewall (for testing purposes only) to see if it resolves the issue.
3. Examine Server Logs: Access the server's logs to identify any errors or warnings related to SSL/TLS connections or other potential problems. These logs will pinpoint server-side issues far more effectively than client-side checks.
4. Inspect Certificates: Verify the server's SSL/TLS certificate is valid, hasn't expired, and is correctly configured. Check for missing intermediate certificates in the chain of trust. Tools like OpenSSL can help with this.
5. Check Client-Side Configuration: Ensure the client's system time is accurate and that its SSL/TLS libraries are up-to-date and not corrupted.
6. Test with Different Clients: Try connecting to the server using different clients (e.g., different browsers or applications) to determine if the problem is client-specific or server-side.
7. Examine DNS Resolution: Use `nslookup` or `dig` to ensure the server's hostname resolves correctly to its IP address.
8. Consider Load Balancers: If load balancers are involved, consult their documentation and logs for potential issues.
Advanced Troubleshooting Techniques for “[Errno 14] Problem Making SSL Connection”
For persistent problems, more advanced techniques may be necessary:
Packet Capture Analysis (tcpdump/Wireshark): Capturing network packets allows for a detailed analysis of the connection establishment process, revealing where the connection breaks down.
SSL/TLS Handshake Debugging: Specialized tools can help debug the details of the SSL/TLS handshake, identifying specific points of failure.
System Resource Monitoring: Monitor CPU usage, memory consumption, and network I/O to identify potential resource bottlenecks that might cause the server to prematurely close the connection.
Conclusion
The "[Errno 14] problem making SSL connection" error often points to network connectivity or configuration issues rather than solely SSL/TLS problems. A systematic approach, starting with basic network checks and progressing to more advanced techniques like log analysis and packet capture, is crucial for effective troubleshooting. Understanding the various layers involved in establishing an SSL/TLS connection is essential to pinpoint the root cause and implement a lasting solution.

| errno 14 problem making ssl connection: Seek You Kristen Radtke, 2021-07-13 From the acclaimed author of Imagine Wanting Only This—a timely and moving meditation on isolation and longing, both as individuals and as a society There is a silent epidemic in America: loneliness. Shameful to talk about and often misunderstood, loneliness is everywhere, from the most major of metropolises to the smallest of towns. In Seek You, Kristen Radtke's wide-ranging exploration of our inner lives and public selves, Radtke digs into the ways in which we attempt to feel closer to one another, and the distance that remains. Through the lenses of gender and violence, technology and art, Radtke ushers us through a history of loneliness and longing, and shares what feels impossible to share. Ranging from the invention of the laugh-track to the rise of Instagram, the bootstrap-pulling cowboy to the brutal experiments of Harry Harlow, Radtke investigates why we engage with each other, and what we risk when we turn away. With her distinctive, emotionally-charged drawings and deeply empathetic prose, Kristen Radtke masterfully shines a light on some of our most vulnerable and sublime moments, and asks how we might keep the spaces between us from splitting entirely. |

| errno 14 problem making ssl connection: Apocalypse Never (resumo) Michael Shellenberger, 2023-04-28 Este livro é um resumo produzido a partir da obra original. A mudança climática é real, mas não é o fim do mundo. Não é sequer nosso maior problema ambiental. Michael Shellenberger tem lutado por um planeta mais verde por décadas. Ajudou a salvar as últimas sequoias ameaçadas do mundo, co-criou o que seria o predecessor do atual Novo Acordo Verde (Green New Deal), além de, juntamente com cientistas climáticos e ativistas, liderar uma ação bem sucedida para manter as usinas nucleares funcionando, assim evitando os famosos picos de emissão. Porém, em 2019, enquanto se alegava que bilhões de pessoas iriam morrer, o que contribuiu para uma ampla crise de ansiedade ― inclusive entre adolescentes ―, como ativista ambiental há anos, afamado especialista em energia e pai de uma adolescente, Shellenberger resolveu que deveria falar mais a respeito a fim de separar a ficção da ciência. Mesmo após anos da atenção dada pela grande mídia, muitos continuam ignorantes quanto aos fatos mais básicos sobre clima. Em boa parte das nações mais desenvolvidas, os picos das emissões de carbono vêm caindo há mais de uma década. O mesmo ocorre quanto aos números de mortes causadas por condições climáticas extremas, que tiveram uma queda de 80% nos últimos quarenta anos, inclusive em nações mais pobres. Além disso, o risco de um superaquecimento da Terra tem se tornado mais improvável graças ao baixo crescimento populacional e a abundância de gás natural. Curiosamente, aqueles que são mais alarmistas quanto aos problemas climáticos também são os que tendem a se opor às soluções mais óbvias. O que está realmente por detrás de todo esse levante apocalítico ambientalista? Estão poderosos interesses financeiros. Há desejo por status e poder. E há, sobretudo, um desejo de transcendência de pessoas supostamente seculares. O impulso espiritual pode ser natural e saudável, porém ao pregar medo sem amor e culpa sem redenção, a nova religião não está satisfazendo nossas mais profundas necessidades psicológicas e existenciais. |
| errno 14 problem making ssl connection: Bowling Alone: Revised and Updated Robert D. Putnam, 2020-10-13 Updated to include a new chapter about the influence of social media and the Internet—the 20th anniversary edition of Bowling Alone remains a seminal work of social analysis, and its examination of what happened to our sense of community remains more relevant than ever in today’s fractured America. Twenty years, ago, Robert D. Putnam made a seemingly simple observation: once we bowled in leagues, usually after work; but no longer. This seemingly small phenomenon symbolized a significant social change that became the basis of the acclaimed bestseller, Bowling Alone, which The Washington Post called “a very important book” and Putnam, “the de Tocqueville of our generation.” Bowling Alone surveyed in detail Americans’ changing behavior over the decades, showing how we had become increasingly disconnected from family, friends, neighbors, and social structures, whether it’s with the PTA, church, clubs, political parties, or bowling leagues. In the revised edition of his classic work, Putnam shows how our shrinking access to the “social capital” that is the reward of communal activity and community sharing still poses a serious threat to our civic and personal health, and how these consequences have a new resonance for our divided country today. He includes critical new material on the pervasive influence of social media and the internet, which has introduced previously unthinkable opportunities for social connection—as well as unprecedented levels of alienation and isolation. At the time of its publication, Putnam’s then-groundbreaking work showed how social bonds are the most powerful predictor of life satisfaction, and how the loss of social capital is felt in critical ways, acting as a strong predictor of crime rates and other measures of neighborhood quality of life, and affecting our health in other ways. While the ways in which we connect, or become disconnected, have changed over the decades, his central argument remains as powerful and urgent as ever: mending our frayed social capital is key to preserving the very fabric of our society. |

| errno 14 problem making ssl connection: Descartes' Error Antonio Damasio, 2005-09-27 Since Descartes famously proclaimed, I think, therefore I am, science has often overlooked emotions as the source of a person’s true being. Even modern neuroscience has tended, until recently, to concentrate on the cognitive aspects of brain function, disregarding emotions. This attitude began to change with the publication of Descartes’ Error in 1995. Antonio Damasio—one of the world’s leading neurologists (The New York Times)—challenged traditional ideas about the connection between emotions and rationality. In this wondrously engaging book, Damasio takes the reader on a journey of scientific discovery through a series of case studies, demonstrating what many of us have long suspected: emotions are not a luxury, they are essential to rational thinking and to normal social behavior. |

| errno 14 problem making ssl connection: Switch Chip Heath, Dan Heath, 2010-02-16 Why is it so hard to make lasting changes in our companies, in our communities, and in our own lives? The primary obstacle is a conflict that's built into our brains, say Chip and Dan Heath, authors of the critically acclaimed bestseller Made to Stick. Psychologists have discovered that our minds are ruled by two different systems - the rational mind and the emotional mind—that compete for control. The rational mind wants a great beach body; the emotional mind wants that Oreo cookie. The rational mind wants to change something at work; the emotional mind loves the comfort of the existing routine. This tension can doom a change effort - but if it is overcome, change can come quickly. In Switch, the Heaths show how everyday people - employees and managers, parents and nurses - have united both minds and, as a result, achieved dramatic results: • The lowly medical interns who managed to defeat an entrenched, decades-old medical practice that was endangering patients • The home-organizing guru who developed a simple technique for overcoming the dread of housekeeping • The manager who transformed a lackadaisical customer-support team into service zealots by removing a standard tool of customer service In a compelling, story-driven narrative, the Heaths bring together decades of counterintuitive research in psychology, sociology, and other fields to shed new light on how we can effect transformative change. Switch shows that successful changes follow a pattern, a pattern you can use to make the changes that matter to you, whether your interest is in changing the world or changing your waistline. |

| errno 14 problem making ssl connection: Staying with the Trouble Donna J. Haraway, 2016-08-25 In the midst of spiraling ecological devastation, multispecies feminist theorist Donna J. Haraway offers provocative new ways to reconfigure our relations to the earth and all its inhabitants. She eschews referring to our current epoch as the Anthropocene, preferring to conceptualize it as what she calls the Chthulucene, as it more aptly and fully describes our epoch as one in which the human and nonhuman are inextricably linked in tentacular practices. The Chthulucene, Haraway explains, requires sym-poiesis, or making-with, rather than auto-poiesis, or self-making. Learning to stay with the trouble of living and dying together on a damaged earth will prove more conducive to the kind of thinking that would provide the means to building more livable futures. Theoretically and methodologically driven by the signifier SF—string figures, science fact, science fiction, speculative feminism, speculative fabulation, so far—Staying with the Trouble further cements Haraway's reputation as one of the most daring and original thinkers of our time. |

Artificial Intelligence helps choose what books you buy, what movies you see, and even who you date. It puts the “smart” in your smartphone and soon it will drive your car. It makes most of the trades on Wall Street, and controls vital energy, water, and transportation infrastructure. But Artificial Intelligence can also threaten our existence. In as little as a decade, AI could match and then surpass human intelligence. Corporations and government agencies are pouring billions into achieving AI’s Holy Grail—human-level intelligence. Once AI has attained it, scientists argue, it will have survival drives much like our own. We may be forced to compete with a rival more cunning, more powerful, and more alien than we can imagine. Through profiles of tech visionaries, industry watchdogs, and groundbreaking AI systems, Our Final Invention explores the perils of the heedless pursuit of advanced AI. Until now, human intelligence has had no rival. Can we coexist with beings whose intelligence dwarfs our own? And will they allow us to? “If you read just one book that makes you confront scary high-tech realities that we’ll soon have no choice but to address, make it this one.” —The Washington Post “Science fiction has long explored the implications of humanlike machines (think of Asimov’s I, Robot), but Barrat’s thoughtful treatment adds a dose of reality.” —Science News “A dark new book . . . lays out a strong case for why we should be at least a little worried.” —The New Yorker |

McDaniel, 2014-04-14 To most of us, learning something the hard way implies wasted time and effort. Good teaching, we believe, should be creatively tailored to the different learning styles of students and should use strategies that make learning easier. Make It Stick turns fashionable ideas like these on their head. Drawing on recent discoveries in cognitive psychology and other disciplines, the authors offer concrete techniques for becoming more productive learners. Memory plays a central role in our ability to carry out complex cognitive tasks, such as applying knowledge to problems never before encountered and drawing inferences from facts already known. New insights into how memory is encoded, consolidated, and later retrieved have led to a better understanding of how we learn. Grappling with the impediments that make learning challenging leads both to more complex mastery and better retention of what was learned. Many common study habits and practice routines turn out to be counterproductive. Underlining and highlighting, rereading, cramming, and single-minded repetition of new skills create the illusion of mastery, but gains fade quickly. More complex and durable learning come from self-testing, introducing certain difficulties in practice, waiting to re-study new material until a little forgetting has set in, and interleaving the practice of one skill or topic with another. Speaking most urgently to students, teachers, trainers, and athletes, Make It Stick will appeal to all those interested in the challenge of lifelong learning and self-improvement. |

| errno 14 problem making ssl connection: Elements of Causal Inference Jonas Peters, Dominik Janzing, Bernhard Scholkopf, 2017-11-29 A concise and self-contained introduction to causal inference, increasingly important in data science and machine learning. The mathematization of causality is a relatively recent development, and has become increasingly important in data science and machine learning. This book offers a self-contained and concise introduction to causal models and how to learn them from data. After explaining the need for causal models and discussing some of the principles underlying causal inference, the book teaches readers how to use causal models: how to compute intervention distributions, how to infer causal models from observational and interventional data, and how causal ideas could be exploited for classical machine learning problems. All of these topics are discussed first in terms of two variables and then in the more general multivariate case. The bivariate case turns out to be a particularly hard problem for causal learning because there are no conditional independences as used by classical methods for solving multivariate cases. The authors consider analyzing statistical asymmetries between cause and effect to be highly instructive, and they report on their decade of intensive research into this problem. The book is accessible to readers with a background in machine learning or statistics, and can be used in graduate courses or as a reference for researchers. The text includes code snippets that can be copied and pasted, exercises, and an appendix with a summary of the most important technical concepts. |
| errno 14 problem making ssl connection: Implementing Service Level Objectives Alex Hidalgo, 2020-08-05 Although service-level objectives (SLOs) continue to grow in importance, there’s a distinct lack of information about how to implement them. Practical advice that does exist usually assumes that your team already has the infrastructure, tooling, and culture in place. In this book, recognized SLO expert Alex Hidalgo explains how to build an SLO culture from the ground up. Ideal as a primer and daily reference for anyone creating both the culture and tooling necessary for SLO-based approaches to reliability, this guide provides detailed analysis of advanced SLO and service-level indicator (SLI) techniques. Armed with mathematical models and statistical knowledge to help you get the most out of an SLO-based approach, you’ll learn how to build systems capable of measuring meaningful SLIs with buy-in across all departments of your organization. Define SLIs that meaningfully measure the reliability of a service from a user’s perspective Choose appropriate SLO targets, including how to perform statistical and probabilistic analysis Use error budgets to help your team have better discussions and make better data-driven decisions Build supportive tooling and resources required for an SLO-based approach Use SLO data to present meaningful reports to leadership and your users |
| errno 14 problem making ssl connection: Being Wrong Kathryn Schulz, 2011-01-04 To err is human. Yet most of us go through life assuming (and sometimes insisting) that we are right about nearly everything, from the origins of the universe to how to load the dishwasher. In Being Wrong, journalist Kathryn Schulz explores why we find it so gratifying to be right and so maddening to be mistaken. Drawing on thinkers as varied as Augustine, Darwin, Freud, Gertrude Stein, Alan Greenspan, and Groucho Marx, she shows that error is both a given and a gift—one that can transform our worldviews, our relationships, and ourselves. |
| errno 14 problem making ssl connection: A Monster Calls Patrick Ness, Siobhan Dowd, 2013-08-27 NOW A #1 NEW YORK TIMES BESTSELLER! An unflinching, darkly funny, and deeply moving story of a boy, his seriously ill mother, and an unexpected monstrous visitor. At seven minutes past midnight, thirteen-year-old Conor wakes to find a monster outside his bedroom window. But it isn’t the monster Conor’s been expecting-- he’s been expecting the one from his nightmare, the nightmare he’s had nearly every night since his mother started her treatments. The monster in his backyard is different. It’s ancient. And wild. And it wants something from Conor. Something terrible and dangerous. It wants the truth. From the final idea of award-winning author Siobhan Dowd-- whose premature death from cancer prevented her from writing it herself-- Patrick Ness has spun a haunting and darkly funny novel of mischief, loss, and monsters both real and imagined. |
| errno 14 problem making ssl connection: Wild Problems Russ Roberts, 2022-08-09 From the host of EconTalk, a guide to decision-making when you can't crunch the numbers Algorithms and apps analyze data and tell you how to beat the traffic, what books to buy, what music to listen to, and even who to date—often with great results. But what do you do when you face the big decisions of life—the wild problems of who to marry, whether to have children, where to move, how to forge a life well-lived—that can’t be solved by measurement or calculation? In Wild Problems, beloved host of EconTalk Russ Roberts offers puzzled rationalists a way to address these wild problems. He suggests spending less time and energy on the path that promises the most happiness, and more time on figuring out who you actually want to be. He draws on the experience of great artists, writers, and scientists of the past who found creative ways to navigate life’s biggest questions. And he lays out strategies for reducing the fear and the loss of control that inevitably come when a wild problem requires a leap in the dark. Ultimately, Roberts asks us to see ourselves and our lives less as a problem to be solved than a mystery to be experienced. There's no right decision waiting to be uncovered by an app or rational analysis. Reality is harder than that and, perhaps, a little more interesting. |

| errno 14 problem making ssl connection: Hooked Nir Eyal, 2014-11-04 Revised and Updated, Featuring a New Case Study How do successful companies create products people can’t put down? Why do some products capture widespread attention while others flop? What makes us engage with certain products out of sheer habit? Is there a pattern underlying how technologies hook us? Nir Eyal answers these questions (and many more) by explaining the Hook Model—a four-step process embedded into the products of many successful companies to subtly encourage customer behavior. Through consecutive “hook cycles,” these products reach their ultimate goal of bringing users back again and again without depending on costly advertising or aggressive messaging. Hooked is based on Eyal’s years of research, consulting, and practical experience. He wrote the book he wished had been available to him as a start-up founder—not abstract theory, but a how-to guide for building better products. Hooked is written for product managers, designers, marketers, start-up founders, and anyone who seeks to understand how products influence our behavior. Eyal provides readers with: • Practical insights to create user habits that stick. • Actionable steps for building products people love. • Fascinating examples from the iPhone to Twitter, Pinterest to the Bible App, and many other habit-forming products. |
| errno 14 problem making ssl connection: Shape Jordan Ellenberg, 2021-05-25 An instant New York Times Bestseller! “Unreasonably entertaining . . . reveals how geometric thinking can allow for everything from fairer American elections to better pandemic planning.” —The New York Times From the New York Times-bestselling author of How Not to Be Wrong—himself a world-class geometer—a far-ranging exploration of the power of geometry, which turns out to help us think better about practically everything. How should a democracy choose its representatives? How can you stop a pandemic from sweeping the world? How do computers learn to play Go, and why is learning Go so much easier for them than learning to read a sentence? Can ancient Greek proportions predict the stock market? (Sorry, no.) What should your kids learn in school if they really want to learn to think? All these are questions about geometry. For real. If you're like most people, geometry is a sterile and dimly remembered exercise you gladly left behind in the dust of ninth grade, along with your braces and active romantic interest in pop singers. If you recall any of it, it's plodding through a series of miniscule steps only to prove some fact about triangles that was obvious to you in the first place. That's not geometry. Okay, it is geometry, but only a tiny part, which has as much to do with geometry in all its flush modern richness as conjugating a verb has to do with a great novel. Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face. Geometry asks: Where are things? Which things are near each other? How can you get from one thing to another thing? Those are important questions. The word geometrycomes from the Greek for measuring the world. If anything, that's an undersell. Geometry doesn't just measure the world—it explains it. Shape shows us how. |

The twenty-fifth anniversary edition of this modern classic will continue to spark creative minds for years to come. Anne Lamott is a warm, generous, and hilarious guide through the writer’s world and its treacherous swamps (Los Angeles Times). “Superb writing advice…. Hilarious, helpful, and provocative.” —The New York Times Book Review For a quarter century, more than a million readers—scribes and scribblers of all ages and abilities—have been inspired by Anne Lamott’s hilarious, big-hearted, homespun advice. Advice that begins with the simple words of wisdom passed down from Anne’s father—also a writer—in the iconic passage that gives the book its title: “Thirty years ago my older brother, who was ten years old at the time, was trying to get a report on birds written that he’d had three months to write. It was due the next day. We were out at our family cabin in Bolinas, and he was at the kitchen table close to tears, surrounded by binder paper and pencils and unopened books on birds, immobilized by the hugeness of the task ahead. Then my father sat down beside him, put his arm around my brother’s shoulder, and said, ‘Bird by bird, buddy. Just take it bird by bird.’” |
