[OOD-users] Interactive desktop question

[Martin Cuma]

Hello,

we are adding our new cluster to our OOD instance (running version 1.3), 
and, we're not having luck getting the interactive desktop running, while 
in our older clusters this works fine.

The job gets submitted, VNC session gets created, I can run vncviewer on 
another machine to connect to it, but, it's not relayed to the OOD 
webserver (VNC in the OOD browser window says "Failed to connec to 
server". The settings are the same between the two clusters, the logs 
look more-less the same (output.log, vnc.log in the 
.../bc_desktop/.../output directory).

The compute nodes on these two clusters should run essentially the same OS 
images, and there are no firewalls on the compute nodes.

We followed https://github.com/novnc/noVNC/wiki/Troubleshooting to see 
what the browser returns, and, for the session with the error we see:

Can someone please try to decipher this error message and/or have any 
suggestions what else we can look at?

Thanks,
MC
