Main problem, you post to x2go-dev _and_ x2go-user and you are not  
subscribed to x2go-user. If people reply on x2go-user, you are not in  
the list of recipients.

ahhh... make sure CUPS operates on IPv4. Obviously, there is a problem  
with IPv6 on your system (maybe disabled?).

IPv6 is disabled by this (on Debian/Ubuntu):
echo net.ipv6.conf.all.disable_ipv6=1 > /etc/sysctl.d/disableipv6.conf
