git 提示：kex_exchange_identification: Connection closed by remote host Connection closed by 39.152.16.167 port错误的解决办法

使用 git push 推送代码时，遇到如下错误：

$ git push -u origin master
kex_exchange_identification: Connection closed by remote host
Connection closed by 39.152.16.167 port 22
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

产生这个错误一般都是网络问题，比如临时网络波动或者使用了代理上网，比如VPN之类的。等一会网络恢复或关闭代理后重新推送即可。

如果网络一直有问题或关闭代理后仍然无法推送，那么可以将 SSH 方式切换成 HTTPS 方式。

将 SSH 改为 HTTPS 格式的远程库：

git remote set-url origin https://github.com/www_02405_com/xxx.git

这样就可以正常推送了。
