Git Push Error: 'SSL_ERROR_SYSCALL' - Troubleshooting Guide

This error message indicates that Git is unable to establish a secure connection with the GitHub server. The cause of this error could be due to multiple reasons, such as network connectivity issues, outdated SSL certificates, or firewall restrictions.

To resolve this error, you can try the following solutions:

1. Check your network connection and ensure that you have a stable internet connection.
2. Verify if your SSL certificates are up-to-date and not outdated. You can update your SSL certificates by downloading them from your certificate authority website.
3. Try disabling any firewall or antivirus software that could be blocking the connection.
4. Try using SSH instead of HTTPS to push your changes. You can set up SSH by generating a new SSH key, adding it to your GitHub account, and configuring your local Git repository to use SSH.

If none of these solutions work, you can contact GitHub support for further assistance.
