【解决方法】git pull报错ssh: connect to host github.com port 22: Connection timed out

问题

git pull
ssh: connect to host github.com port 22: Connection timed out
fatal: Could not read from remote repository.

解决方法

在C:\Users\username.ssh文件夹下新建config文件，填入以下文本（如有则直接在文件最后一行新增）：

Host github.comHostname ssh.github.comPort 443

将22端口修改为443即可。
验证：

ssh -T [e-mail]

出现Hi xxxx! You've successfully authenticated, but GitHub does not provide shell access.即正常。
