Hi all!
I was using x2go on my notebook on a IPv6 enabled network and the x2goserver also has v6 connectivity. Everything went fine so far, however when I am in an IPv4 only network (no v6 default route, only link-local address) x2go to the same server fails with "Connection timed out" while I am able to connect to the x2goserver flawlessly via ssh over IPv4. If I start the local v6tunnel on my notebook connecting to the x2goserver works again.
Regards
Christoph
