kex_exchange_identification 问题：读取：连接被对等方重置

Question

我在使用我大学的 VPN 从 Macbook 将我的 Web 应用程序（大学项目）部署到 Ubuntu Server 的过程中遇到问题。这是我第一次部署软件，所以这对我来说有很多新东西。

我试图将服务器配置为与 localhost (127.0.0.1) 一起使用，然后我无法再连接到 ssh，并显示此错误消息：

reynaldjhonson@Reynalds-MacBook-Air ~ % ssh [email protected]
kex_exchange_identification: read: Connection reset by peer
Connection reset by 10.197.245.113 port 22

这是我的 ssh -v

reynaldjhonson@Reynalds-MacBook-Air ~ % ssh [email protected] -v

和 telnet

telnet 10.197.245.113 22
Trying 10.197.245.113...
Connected to swtp-ekg.ges.thm.de.

Connection closed by foreign host.

我已经阅读了很多解决方案在互联网上给出了更改服务器中的某些conf文件的方法，但我什至无法从我的Macbook访问服务器。

我真的很感谢任何帮助或提示！ 谢谢！
