HI All,
A user of our system recently come with the following errors while trying to use X2go client on Windows 10.
=== Info: Forwarding X11 connections to display 'localhost:0'. Session: Session started at 'Thu Feb 14 12:51:37 2019'. Warning: Protocol mismatch or no X authentication data.
Session: Terminating session at 'Thu Feb 14 12:51:41 2019'. Info: Your session was closed before reaching a usable state. Info: This can be due to the local X server refusing access to the client. Info: Please check authorization provided by the remote X application. Session: Session terminated at 'Thu Feb 14 12:51:41 2019'.
We are running X2go servers on CentOS 6 Linux; other clients (MacOS, other users with Windows 7 and 10) seem to connect fine. So the problem likely is with the client. I believe the Windows x2go client comes with an X11 server bundled with it and configured.
Could anyone suggest what could be the reason for such errors, have anyone encountered them before? Any advice much appreciated! Thanks!

If it's only happening on one client, my guess would be that the client installation is broken somehow.
This could be just about anything - hardware failure (disk, RAM), malware, an overzealous AntiVirus, or just a plain misconfiguration or filesystem error.
The easiest way would probably be to create another user account on the same client and try it with that one - to see if the problem is with the user or the machine. To cross-check, have the affected user try to log in using X2GoClient on a different machine.
If the problem persists and is tied to the machine, the next try would be to perform a clean uninstall of X2GoClient, reboot, then reinstall X2GoClient from a newly downloaded copy of the installer.
If it's tied to the user, compare group memberships both on the client and on the server side between the affected user and a user having no issues, also, let the user try to log in using plain SSH (PuTTY) and possibly with X-Forwarding and a manually started X-Server on the client, to see if the issue is with X2Go or with the underlying operating system/permissions/whatever.

Have you cleaned out the .x2go folder in the user accounts?

Hi Stefan,
Yes, I have tried that, deleting .x2go folder and .xsession-x2go*errors and .Xauthority in their $HOME
Looks like it didnt help (the user still fails to connect, there is no new .x2go folder there ).

Hi Grigory,
That wasn't my suggestion, but Paul's.
What about my suggestions? Have you tried any of those?
