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!
