I know where to find a typical log file, VNC logs are missing in /var/log. That’s the reason I post question for help. Could you maybe try the provided only three reproduce steps yourself to see what is going on?

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.
