Thanks!

The client OS is in fact Windows, and I think they only have single user
(like home edition or whats it called). We have tried connecting via putty
and straight SSH works. We have tried giving x2go client a standalone
VcxSrv but didn¹nt help.

Is there a , I guess, well defined setting (local port(s) for X11?) to
specifically check Antivirus for?
