Hi I use the Azure Marketplace Cloud Image version 1.3.2101272359
i don't installed any plugin or modified any configuration file.
If i connect via RDP Protocol to a VM with Apache Guacamole my connection to the desktop enviornment will instantly closed with the message: DISCONNECTED You have been disconnected. SSH Protocol is working fine.
The logs of my RDP VM (xrdp-sesman) says:
myuser@hostname:/var/log$ tail -f xrdp-sesman.log

FYI: connecting via MSTSC to the RDP VM is working as expected. So i think there is an issue with Guacamole.
Do you need further logs or informations? Greetz
