Assunto: x2gostartagent: X2Go Agent terminated unexpectedly

Package: x2goserver
Version: 4.1.0.3-0.0


Hello,
I have a server (Centos 6) with Gnome, SSH and X2goServer.
The accesses by SSH is ok, but X2goClient (4.1.2.0 - Windows) do not work.
On server-side, I have this message: "/usr/bin/x2gostartagent: Failed to start X2Go Agent session with ID elder2-50-1568998198_stDGNOME_dp32. X2Go Agent terminated unexpectedly. Aborting session startup."
Can you help me?
