noVNC "Failed to connect to server" after upgrade to 13.0

[wuxia]

After upgrading to 13.0 I can no longer connect to my Debian VM. Using noVNC gives me "Failed to connect to server". If I boot back to 12.0-U8.1 everything works fine. Is this a bug or somehow 13.0 is more picky about hardware? My CPU is Xeon D-1520.

Known bug in 13: only port 5900 works for any VNC connection.

Thanks, it worked. I guess that means you can have only one active VNC vm at the same time which is kind of unfortunate.
