VNC console not working on clustered nodes

[ironicbadger]

Hi,

New cluster just created and the node I'm logged into via the web console, VNC works fine. Any of the other clustered nodes VNC does not.

If I login the Promox UI hosted by that specific node, it works. I.e. the clustered node can view VNC from all nodes. But the 'master' node can only see VMs hosted on itself.

Any ideas?

did you change the ssh config? we rely on ssh for tunneling the vnc connection

I found a few threads and tried a few things yes (I've confused myself a little so not sure what I have / haven't tried anymore). Is there an article you can link to?

no there is no article, but important is that the nodes can ssh with 'ssh root@ip-of-the-nodes' without using a password/port
and that the sshd_config allows LC_PVE_* or LC_* environment variables and the ssh_config sends them
