> VNC Connections not working after upgrade to 1.5.0 (docker official images)

> Issue Type: Bug
> Components: guacd-docker
> Affects Versions: 1.5.0

> Reporter: James Freeman

> Hi there
> I have been running Guacamole in the official Docker containers since version
> 1.4.0, and it has always been rock solid. I recently upgraded to the new
> release of 1.5.0 as I wanted the new SSH support available to connect to my
> Ubuntu 22.04 hosts without reconfiguring them.
> Since the upgrade, the RDP and SSH connections work perfectly, but VNC
> connections (which previously worked in 1.4.0) no longer work. I have
> confirmed I can still connect using a normal VNC viewer without issue, so am
> confident in the VNC server operation and password. In the guacd container
> logs, I see:
