My Ubuntu Desktop 22.04.4 LTS lost its XRDP access and I'm unable to figure out how to solve it. XRDP service is running, no errors in XRDP logs.
netstat -an | grep "LISTEN " | grep ":3389"
tcp6 0 0 :::3389 :::* LISTEN
All looks fine locally for the XRDP. The UFW is off. I think iptables are blocking it, but unable to figure out why. I've added an exception for 3389, but still no luck. The iptable list can be found here: https://pastebin.com/yAK1b0Fj

I've deployed and configured this machine in Azure. It was handed over to the developer to run Docker containers.
I'm testing RDP form Windows VM on the same LAN. Can ping it and SSH to it, but RDP is not working any more.
Help would be greatly appreciated. Please let me know if you would like any additional details.
