Git 报错：SSH连接超时

问题

使用 Git 向 GitHub 部署代码时，报错如下（此前正常）：

ssh: connect to host github.com port 22: Connection timed out
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.

原因

SSH 端口被占用，重新指定一个端口即可。

注：Windows 系统查看端口占用情况的命令为：netstat -ano | findStr 端口号

解决

• 打开 C:\用户\主机名\.ssh 文件夹

• 新建 config 文件（不带后缀）

• 输入以下内容后保存：

  Host github.com
  User GitHub注册邮箱
  Hostname ssh.github.com
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/id_rsa
  Port 443

• 在 Git Bash 执行：

  ssh -T git@github.com

  出现询问是否连接的提示，输入 yes 回车：

  $ ssh -T git@github.com
  The authenticity of host '[ssh.github.com]:443 ([20.205.243.160]:443)' can't be established.
  Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
  Warning: Permanently added '[ssh.github.com]:443' (ED25519) to the list of known hosts.
  Hi x-Parker! You've successfully authenticated, but GitHub does not provide shell access.

  成功重新建立 SSH 连接。

另解

抛弃 SSH 连接方式，使用 HTTPS 连接 Github。
