Hi,

I'm attempting to setup a 3-node Proxmox cluster via the GUI.

I have a separate network for Corosync.

My VM IP addresses are 10.0.12.3, 10.0.12.4 and 10.0.12.5.

My Corosync IP addresses are 10.0.19.3, 10.0.19.4 and 10.0.19.5.

On the first node, I was able to create one successfully, setting the ring0 address to 10.0.19.3.

On the second node - I attempted to join the first node's cluster - however, I get the error:

Code:
Connection error 500: RPCEnvironment init request failed: Unable to load access control list: Connection refused

In this case, I had set the ring0 address to 10.0.19.4 (since that is the ring0 address I wanted node 2 to use).

Any ideas what's going on?
 
are pve-cluster and corosync up and running?

systemctl status pve-cluster corososync
