Unexpected need for a server side proof of life to maintain or open an xrdp session if running Gnome?

I installed xrdp on a Debian-12.5.0-amd64 with the Gnome windows manager:

sudo apt update && sudo apt upgrade
sudo apt-get install xrdp
systemctl status xrdp
sudo adduser xrdp ssl-cert
systemctl restart xrdp

/etc/xrdp/sesman.ini is configured as such: [Sessions] ... KillDisconnected=false DiconnectedTimeLimit=0 IdleTimeLimit=0 I can connect using windows remote desktop and it works well, but the session freezes and then disconnects after a few minutes of inactivity saying that the session is over. I need to type on the server keyboard for the client to be able again to join the remaining session. - How to maintain the ability to open xrdp session without timeout? - How to work with a remote headless server, not requiring a local proof of life? Regards. Note that if using Xfce instead of Gnome, or if using Gnome on Ubuntu instead of Debian, the problem does not occur!
