Github无法push代码报Connection closed

背景

突然间代码 push 不上去，报如下错误：

Connection closed by 140.82.113.4 port 22
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

发现有人也遇到过类似的问题，原因是 22 端口的问题

解决

解决方法参考
https://docs.github.com/zh/authentication/troubleshooting-ssh/using-ssh-over-the-https-port

修改 ~/.ssh/config这个文件，添加以下内容

Host github.com
    Hostname ssh.github.com
    Port 443
    User git
