others-how to solve 'SSL_ERROR_SYSCALL in connection to github.com:443 ' when pushing code to github.com?

1. Purpose

In this post, I would demo how to solve the below error when we trying to push code using git to github.com.

➜  bswen-springboot24 git:(main) git push         
fatal: unable to access 'https://github.com/bswen/bswen-springboot24.git/': LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github.com:443 

2. Environment

  • Mac OS or Linux System

3. The solution

3.1 What does this error mean?

SSL_ERROR_SYSCALL indicates that some problem happened with the underlying I/O (Should be TCP in this case).

3.2 The solution #1

You should try to disable your local proxies that used to connect to github.com.

Try this command:

➜  bswen-springboot24 git:(main) git config --global --unset http.proxy

Or this command:

git config --global --unset http.proxy
git config --global --unset https.proxy

Now try again to push your code to github:

➜  bswen-springboot24 git:(main) git push

   bdffeeb..69a008e  main -> main
➜  bswen-springboot24 git:(main) 

Now it works!
