Github突然连接不上

Question

My github suddenly failed to connect 

$ git push
ssh: connect to host github.com port 22: Connection refused
fatal: Could not read from remote repository.

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

尝试过

$ ssh -T -p 443 git@ssh.github.com
Hi alinbxSorcerer! You've successfully authenticated, but GitHub does not provide shell access.

有什么问题，多年来一直运行良好。

Answer 1

也许您所在的网络阻塞了端口 22。

设置 ssh 从现在起始终为 Github 使用端口 443:

将以下内容添加到您的 .ssh/config 文件中:

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

另一个选项是切换到使用 https 存储库 url，但我觉得时不时地输入密码很烦人。
