I can connect from a client to my server.

I am able to connect but several seconds ~30 my session freeze and x2go ask me for terminate my session. 
Tried with several versions of client, with same issue. Also tried disable audio, file sharing,clipboard,keyboard settings, and run with administrator privileges, disable firewall.

This happens even when no other sessions are running on the client machine.

Debug says : http://pastebin.com/837xZS97

I reported this on IRC they told me create ticket cause this can be a bug.

Best,

JK
