This error can occur for various reasons, and in this article, we'll look at some of the causes of this error and provide code examples to help you troubleshoot and resolve the issue.

What is OpenSSL SSL Connect Error?

OpenSSL is an open-source cryptography library that provides Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols for encrypted communication over the internet. The "OpenSSL SSL connect error" occurs when a client (such as a web browser or Git) is unable to establish a secure connection to a server (such as GitHub.com) using SSL or TLS protocols. This can be caused by several reasons, including network issues, firewall configurations, or problems with the certificate used by the server.

Why the Error Occurs When Connecting to GitHub.com 443?

GitHub.com uses port 443 for secure HTTPS connections. When the "Fatal error: Unable to access OpenSSL SSL connect connection was reset in connection to GitHub.com 443" occurs, it means that there's a problem with the SSL/TLS connection between your client and the GitHub.com server.
