Hello,
I have almost the same problem.
I had 1 proxmox machine (proxmox1). Then i have installed a second one (proxmox2). Then i have created a cluster on the first machine.
When i try to add the second machine to this cluster, it does not work. Neither via GUI nor via command line.

In GUI it gives me "Connection error 401: permission denied - invalid PVE ticket" and kills the GUI, web server is no longer accessible.

Jul 08 17:56:48 proxmox2 pmxcfs[68414]: [main] notice: unable to acquire pmxcfs lock - trying again
------------------------------------------------------------------------------------------------------------------------
systemctl stop pve-cluster
deleting the /var/lib/pve-cluster/.pmxcfs.lockfile
systemctl start pve-cluster
does not change anything. The lockfile reappears, and the node is not working.
All containers are stopped and cannot be started: "cluster not ready - no quorum? (500)"
------------------------
This problem is very common, clusters go mad and fail miserably with these same errors, I tried other related posts, and nothing helps.
Why this cluster thing is so weak and unreliable??? Nobody would want this solution for PRODUCTION, if it fails so easily and cannot be repaired?
In my case the cluster cannot even be built in the first place! Many people have asked to rewrite this whole cluster portion of the code, and for the reason.
Do you have any working solutions, please?

Hello,
That was when i started building a cluster. I had different errors. Then i have upgraded proxmox to the latest version and these errors stopped showing up. About july 2022 i have succeeded building the cluster. The problem was my LAN, presumably. I had 3 switches in between the nodes, and cluster communication (corosync, i think) failed between them. As soon as i have moved the second node to the same switch as the first node, the cluster started working.
The switch configuration was basic, no apparent filtering, multicast enabled, as far as i know. I have never found the root cause of my network-related problem.
