(base) ➜  test git:(dev) git pull
kex_exchange_identification: Connection closed by remote host
Connection closed by 192.30.255.113 port 22
致命错误：无法读取远程仓库。

解决方案

参照下边文档
https://docs.github.com/en/authentication/troubleshooting-ssh/using-ssh-over-the-https-port

• 进入config文件

(base) ➜  .ssh vi ~/.ssh/config

• 添加下述配置

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

• 结果如下图
  
• 运行如下代码进行验证

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

• 如果都没问题，重新git pull自己代码仓库里的代码，发现可以正常拉取，问题至此解决
