Connected to 172.100.90.199. Escape character is '^]'. Connection closed by foreign host.v

根据提供的引用内容分析，"Connection closed by foreign host" 是一个连接被远程主机关闭的错误信息。这通常意味着连接尝试过程成功建立，但随后被远程主机关闭了。这可能是由于以下几个原因引起的：

1. 远程主机上的服务未正确配置或未启动。您需要确保对应的服务已经启动并正常运行。

2. 防火墙或网络设置可能会阻止连接，您需要检查防火墙规则和网络配置。

3. 远程主机上的服务可能因为某种错误或异常而自动关闭了连接。这可能是由于资源不足、内存泄漏或其他问题引起的。您可以尝试重启服务或远程主机来解决此问题。

请检查以上几点并尝试解决问题，如果问题仍然存在，请提供更多详细信息以便进一步分析和帮助解决。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
