Having a similar problem running on Ubuntu 22.04 with both Debian images. For both I can connect via the noVNC browser but not with TigerVNC directly. The rocky-xfce-vnc image works via both connection methods.

Log from docker run -p 5901:5901 -p 6901:6901 consol/debian-xfce-vnc --debug bash with a connection via noVNC at the end (attempting to connect via TigerVNC shows nothing in the container log).

Hi All,

I also faced with same issue. The cause of this issue is that vnc server must be started with parameter "-localhost no". The author fixed it in debian xfce Dockerfile, but seems he forgot to rebuild and push new docker image to Docker registry. I cloned this project and rebuild it localy and it works fine.

Here it is explained and fixed #165

sni · 2023-04-30T14:49:16Z

should be fine with :latest now as well.

sni · 2023-07-05T07:57:14Z

what kind of error do you get? The $STARTUPDIR (/dockerstartup) should be writable und normal conditions.

4hiziri · 2023-07-11T03:00:04Z

Sorry, that is my misunderstanding. Please forget it.
