Local node times out

[greg]

Greetings

I have a 6-nodes cluster running Proxmox 6.3.3. When I connect on a GUI, all nodes are green, except one, which has a little grey "?". I can connect on this node: on the GUI, I see the same thing (i.e. the local node is "?", all other nodes are green and can be managed).
With the CLI, trying "pct" just hangs the terminal (ctrl-c not working).

What should I do?

Thanks in advance

Regards

First do some basic checks:

1. Can you (at least) ping the "problem node" from the "good nodes"?
2. Can you (at least) ping the "good nodes" from the "problem node"?
3. Are you using DHCP or static IP?
4. Are all the nodes in the same switch/router?
5. Did you tried to plug a "good node" in the same switch/router port as the "problem node"? If yes, were you still able to join the cluster?

Thanks for your answer.
It's not a network problem (I can manage all nodes from the "grey" one), more something at the CT supervisor level, as I cannot do a "pct list" locally in ssh.
Maybe I can restart a deamon, but I'm not sure which one...

First try the 5 points above, sometimes even experienced users can make very trivial mistakes.

Also try to `curl` from a good node to the bad node's 8006 port and see if you can get a proper reply.

I just restarted the daemon, it was stuck somehow, everything else was working ok.
