Howdy,

	When I connect from Mac client to ubuntu server, I get a “connection timeout” 30 seconds after “connection start.”  Other people can connect to my server.

Error message is:
Loop: WARNING! Overriding auxiliary X11 port with new value '1'.

On the server, in /var/log/messages, I get what appears to be a success report:
Mar 19 09:38:16 hpnsw4371 /usr/bin/x2gostartagent: successfully started X2Go Agent session with ID charletr-50-1616171893_stDMATE_dp32


I have a tcpdump (is in an ssh tunnel, to a little vague) which shows client sending dup packet not quite, but almost 30 seconds into session attempt.
