Re-installing your server is the same as redoing the servers ssh-key. And as a 
changing ssh-key of the server could mean that your connection is intercepted 
by a man-in-the-middle, ssh stops working at that step and shows you some 
hints what you might do to correct it.
Please use ssh from a terminal (konsole, xterm, whatever) and watch the output 
when connecting to your server. Then follow whats written there.

What does ssh have to do with your x2go-problem? ssh is what is happening on 
the transport-layer below the nx/x2go-protocols to create a secure and trusted 
connection.

Have fun,

Arnold
