So I installed Proxmox on 5 hosts (same image 9.0-1) and started to setup a cluster configuration which worked on the first two hosts and when I attempted on the third host - it timed out with error message:

pve-ssl.pem does not exist! 500

And I checked to see that for some reason I can't access the first host either. At this point, I googled to find some advise asking me to run
Code: 
 pvecm updatecerts --force
which didn't work as it's just hung on 'generate new node certificate' on the first host and on the third, it's 'waiting for pmxcfs mount to appear and get quorate' and times out.

I can only access the second host via GUI but I can access all three via SSH - no idea what's happening and why? Appreciate any help.

Hello,

If you have ssh access run:

pvecm delnode nodefordelete

Checking remaining nodes, if still exist:

pvecm nodes.

Manual removal :

systemctl stop pve-cluster
systemctl stop corosync
rm -rf /etc/pve/corosync.conf
rm -rf /etc/corosync/*
rm -rf /var/lib/pve-cluster/*

Try adding the nodes again.
 
Okay, I got through to the GUI by running updatecerts command again on all nodes. And I created the cluster in the first node and tried to join on the second node but now I get the following error:

TASK ERROR: fingerprint 'XX:XX:XX:XX:XX' not verified, abort!

you seem to be missing your fingerprint it seems11:12:AA:AA:AA:AA:AA:AA:AA:AA: you can get it from pve-ssl.pеm from the node to which you will join another node and put it in the new node

I replaced my fingerprint above, sorry I should have mentioned that.

But I had to reboot all the servers and it worked fine after that.
