出错信息
报错：fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
本质原因
尝试使用 git bash ssh -T git@github.com命令后报错：
ssh: connect to host github.com port 22: Connection timed out

在C:\Users\Administrator.ssh 下加入 config 文件（无后缀）内容：
Host github.com
User 472287500@qq.com
Hostname ssh.github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
