to narrow down this issue, please try these steps:

1=C2=A0 o enable loglevel=3Ddebug in /etc/x2go/x2goserver.conf, what do= you see in
=C2=A0 =C2=A0 /var/log/messages?
2=C2=A0 o use a Linux X2Go Client
3= =C2=A0 o use PyHoca-GUI or PyHoca-CLI as client application for X2Go on a L= inux
=C2=A0 =C2=A0 machine (with --libdebug option on the cmdline)
4=C2=A0 o = btw. do you actually see the session window (for desktop sessions)
=C2=A0 =C2=A0 appear? (and then disappear?)
5=C2=A0 o try ssh user@serve= r -X nxagent :20 (does nxagent come up?)

We have to find out, if your crash is an X2Go Server bug or an NX bug on EP= EL-7.

Thanks+Greets,
Mike
