Sounds like you setup an Ubuntu container to run the VNC server in. So, in Linux the log files
typically go in the directory /var/log. You could look there. Try this to look for files with
vnc entries: grep vnc /var/log/* -R | less


You could also try tailing the messages log file in Ubuntu while you try to connect to the
vnc server: tail -f /var/log/messages.log


It might help to see what the vnc server is logging when you try to connect with the client.

Hi Changkun,


Could you attach the log from the VNC server?
