无法从远程服务器连接 SSH

我无法通过 SSH 从云服务器连接 sFTP。我使用代理进行连接并允许 IP 地址。当我使用相同的代理从本地服务器连接时，连接成功。这只在我尝试从 Heroku 服务器（基于 AWS 构建）连接时才出现问题。我的日志服务器似乎没什么用。

这是来自云服务器的连接失败关闭连接的地方（使用代理）

这是从我的本地服务器成功建立的连接，与不成功的连接关闭的同一点（使用相同的代理）

这两次连接尝试都是相同的（相同的代理、相同的用户、相同的密钥）。我现在真的很困惑，有人知道我该怎么做才能解决这个问题吗？

确保：远程计算机的 IP 地址正确。SSH 守护程序正在监听的端口未被防火墙阻止或错误转发。您的用户名和密码正确
