Hello,

We've had issues resuming suspended sessions. We connect to a linux server from different client machines (PC and Mac) using x2go. For some reason, after suspending sessions, we cannot resume sessions.

We receive messages such as:

X2Go-52
The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server.

Info: Proxy running in client mode with pid '8xxx'.

Session: Starting session at 'Tue Jan 24 11:17:00 2017'.

Info: Connecting to remote host 'localhost:xxxxx'.

Info: Connection to remote proxy 'localhost:xxxx' established.

Info: Connection with remote proxy completed.

Warning: Unrecognized session type 'unix-kde-depth_32'. Assuming agent session.

Warning: Failed to read data from the X auth command.

Warning: Generated a fake cookie for X authentication.

Warning: Cookie mismatch in the X authentication data.

Session: Terminating session at 'Tue Jan 24 11:17:05 2017'.

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 'Tue Jan 24 11:17:05 2017'.

Connection timeout, aborting

NXPROXY - Version 3.5.0

The only way to resolve this problem is using the following two commands on the server:

rm -rf /tmp/.x2go-username/
rm -rf ~/.x2go/C-username-*

After 2 attempts, we can log into the server using x2go, but a new session is started. The previous open session is terminated.

Is there a reason why this is happening? Is there an option to select during installation/configuration to prevent these resume problems?

Any help would greatly be appreciated.
