On the client, you can run:
x2goclient --debug >~/x2godebug.log 2>&1
On the server, you can edit /etc/x2go/x2goserver.conf and replace
loglevel=notice
with
loglevel=debug
This will increase the verbosity of x2goserver's syslog entries.

You are actually the third to encounter this issue; sadly, the other two
couldn't be bothered to subscribe here to report the bug.
It seems to be a server-side issue, using Ubuntu 20.04 on the server
side is the common part of the reports.
I wonder if maybe there's some kind of sleep/suspend/energy-saver at
work, or maybe some kind of "scrubbing" mechanism (possibly
systemd-related)?
I've seen such issues in the past, in different contexts, where cron
jobs were unaware of a running X2Go session and did "stupid" things
(like shutting down the server) that affected the session - because to
them, it looked like there are no users logged in.
Do you think you could set up a test server with Ubuntu 20.04 that does
not have a GUI, and only some very basic X applications like xterm?
Is gdm (or some other graphical login manager) running on your server?
If so, could you stop it, switch the machine to text-only mode, and see
if that makes a difference?
