请阅读整个问题，底部有一些非常重要的信息！
我正在尝试使用反向 SSH 隧道将所有前往 VPS 端口 25565（IP 地址 XXXX）的流量转发到我家用 PC 的端口 25565（IP 地址 YYYY）。以下是我正在使用的命令：
ssh -f -v -N -T -R25565:localhost:25565 X.X.X.X (on my home PC)
ssh -v -p 25565 kevin@localhost (on my VPS)
但是，第二个命令成功运行并首先连接约 20 秒，但随后退出并显示kex_exchange_identification: Connection closed by remote host。我的 VPS 和家用电脑的文件GatewayPorts=yes都有。sshd_config尝试连接到我的 Minecraft 服务器会导致超时，即使在第二个命令运行的大约 20 秒内也是如此。第一个命令运行良好。
对于我的 VPS，运行sudo tail -n300 /var/log/auth.log | grep "ssh"显示以下内容：

我的问题是：
- 我究竟做错了什么？ （如果有什么）
- 我该如何纠正我的错误？
最终，我最大的问题是如何让反向 SSH 隧道正常工作，以便所有到 XXXX:25565 的 Minecraft 流量都转发到实际服务器运行的 YYYY:25565。
值得注意的是，XXXX 正在运行 OpenVPN，并充当客户端 YYYY 的 OpenVPN 服务器
