If you're facing issues while connecting to Github.com:443, and you're getting the ssl_error_syscall error, then don't worry; you're not alone. This error is usually caused by misconfiguration of SSL/TLS protocols or certificate issues. In this guide, we will walk you through the troubleshooting process and provide you with a step-by-step solution to fix this error.
Troubleshooting the ssl_error_syscall Error
Before we jump into the solution, let's first try to understand the error message. The ssl_error_syscall error is a common SSL/TLS related error that occurs when your SSL/TLS client fails to communicate with the server due to some system call error. This error can occur due to various reasons, such as:
- Outdated SSL/TLS protocols
- Expired or invalid SSL/TLS certificates
- Firewall or proxy issues
- Incorrect system time and date
- Misconfigured SSL/TLS settings
Now that we know the possible causes of the error let's move on to the solution.
Solution: Fixing the ssl_error_syscall Error
To fix the ssl_error_syscall error, follow the steps below:
Update your SSL/TLS protocols: First, make sure that your SSL/TLS protocols are up-to-date. Github.com requires TLSv1.2 or higher. You can use the following command to check the supported protocols on your system:
openssl s_client -connect github.com:443
If your system supports TLSv1.2 or higher, you will see the following output:
New, TLSv1.2, Cipher is ECDHE-RSA-AES128-GCM-SHA256
If your system doesn't support TLSv1.2 or higher, you need to update your SSL/TLS protocols. You can check this link for more information.
Check your SSL/TLS certificates: If your SSL/TLS certificate is invalid or expired, you will face this error. To check your SSL/TLS certificate, use the following command:
openssl s_client -showcerts -connect github.com:443
This command will show you the SSL/TLS certificate chain. Make sure that the certificate is valid, and all the intermediate certificates are installed correctly.
Disable Firewall or Proxy: Sometimes, your Firewall or Proxy can interfere with the SSL/TLS connection. Try disabling your Firewall or Proxy temporarily and see if the error goes away.
Check your system time and date: Incorrect system time and date can cause SSL/TLS errors. Make sure that your system time and date are correct.
Misconfigured SSL/TLS settings: If none of the above solutions work, then you might have misconfigured SSL/TLS settings. Check your SSL/TLS configuration and make sure that they are correct.
