I have seen this once or twice, but it was not reproducible.

What are your settings for SSH authentication in the session profile  
configuration? Can you make a screenshot?

Is ssh-agent running and have you loaded your SSH private keys into  
ssh-agent? Or does pyhoca-gui try to detect some default private key  
file in ~/.ssh?

What hostkey types are configured on the X2Go Server (check  
/etc/ssh/sshd_config, HostKey parameter).

Thanks+Greets,
Mike
