[Solved] Failing to create pve cluster

[millercentral]

I'm trying to do what seems like the most simple thing, but am completely stuck trying to create a cluster for 3 nodes:

I have a clean install of the latest Proxmox on two identical Minisforum MS-01 pcs. I have:

• Ensured time on both machines are in sync
• Added each machine to the others host file
• Successfully SSH-ed from one to another
• Tried multiple browsers, in-private mode, cache clear, etc.
• Re-setup both nodes multiple times

When I create a new cluster on the first device, it creates just fine.
One the second device, I choose Join Cluster, paste in the join information, add the root password of the cluster host node, confirm the link interface and press join.

The UI becomes unresponsive and in the cluster pane behind the job status dialog box it says: permission denied - invalid PVE ticket (401)
If I reload, the UI does not come up at all. On the host node, it shows the node that attempted to join in the Server View pane, but it is greyed-out/not active. Clicking on it gives the following error: Connection error 596: error:0A000086:SSL routines::certificate verify failed. pvecm status on the host shows both nodes.
Rebooting the joining node gets stuck trying to end pvescheduler.service -- after hard rebooting the node UI is unavailable.

I've also tried joining using pvecm add, but it fails in the same way.

I'm pulling my hair out and can't understand what is wrong. These are completely stock setups with a single nic each and no VMs/LXCs set. I haven't tried joining the third node because I don't want to have to re-set it up from scratch as well when/if it fails to join.

Any suggestions? Thanks

Update: Twenty-fifth time appears to the be the charm. Still not sure what was going wrong, but possibly didn't like my 10g port. Rebuilt again using 2.5gb port and now I'm in business. Strange...
