SSH:连接被远程服务器关闭

Question

我正在尝试通过 ssh 登录到我的远程服务器。但是每当我尝试使用 ssh 命令通过终端登录时:

  ssh root@{ip_address}

我得到错误:

 Connection closed by {ip_address}

我检查了主机拒绝和主机允许，文件中没有任何内容。我不明白为什么会这样？

当我改变我的工作站并且 key 被改变时，它发生了。当我尝试 ssh 登录时，它要求添加 key ，我输入 yes 然后它关闭了连接。

有什么办法可以重新连接ssh吗？

感谢您的帮助。

谢谢你。

ssh -v -v -v -v root@{ip_address} 的输出是

有同样的问题，但简单的远程服务器重启有帮助。
