VNC: Failed to connect to server from different ndoe


Well-Known Member

we have a cluster of 20 nodes. VNC is working fine on all nodes, except on one.
When we try to access the "console" of any VM on that problematical node FROM a different node, we keep getting "Failed to connect to server".
But when we open the GUI of the problematical node and try to open the VMs "console" it works fine.

Any ideas?
does the ssh access work to that node?
