So recently updating to latest, Ubunto RDP works when i first lauch from guac but if i close out and try to go back in I only get connecting for only 10 seconds from looking at the Ubunto side(I see the remote icon on the top right), but on the Guac side it only says connecting, then goes to disconnected. I can VNC from unraid no problem and i can RDP from Windows RPD no issue, and if i rollback to guac 1.5.3 the RPD works again. Looks like the issue is with Guac latest. Just an FYI
