SSH Error | kex_exchange_identification: Connection closed by remote host Connection closed by 20.20

运行$ ssh -T [email protected]报错：

kex_exchange_identification: Connection closed by remote host
Connection closed by 20.205.243.166 port 22

解决方案：

1. 检查公钥是否过期
2. 是否使用代理软件（TUN模式代理全局），进而导致本地端口号指向放生改变

方案一： 切换为远程URL为HTTPS，不使用SSH
方案二： 建立配置文件 config 在目录~/.ssh/下,把端口指向443

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