Problem Guacamole RDP on Win10

[Giuffro]

Hi,
after restarting UnRaid and turning everything back on (activity done other times), I found myself unable to connect to my Windows 10 VM via Guacamole and continually attempting to reconnect. From the logs, these warnings continue to be repeated:

I tried to connect with RDP direct to the VM and I connect, too bad that after less than a minute it disconnects the session.

Do you have any idea what may have changed and how to fix it?
I've been hitting my head for days. :-(
