我的 Ubuntu Desktop 22.04.4 LTS 丢失了 XRDP 访问权限，我不知道如何解决它。XRDP 服务正在运行，XRDP 日志中没有错误。
netstat -an | grep "LISTEN " | grep ":3389"
tcp6 0 0 :::3389 :::* LISTEN
对于 XRDP 来说，本地一切正常。UFW 已关闭。我认为 iptables 阻止了它，但无法找出原因。我为 3389 添加了例外，但仍然没有运气。iptable 列表可以在这里找到： https://pastebin.com/yAK1b0Fj

我已经在 Azure 中部署并配置了这台机器。它被交给开发人员来运行 Docker 容器。
我正在同一 LAN 上测试 Windows VM 的 RDP。可以 ping 通它并通过 SSH 连接到它，但 RDP 不再起作用。
非常感谢您的帮助。如果您需要更多详细信息，请告诉我。
