Fail to set up Cluster

[StellarStallion]

Hi,

I'm trying to set up a Proxmox Cluster on my Laptop, across 3 VMs.
When I try to join with Node2, it never finishes, I need to reload the Webinterface of Node2, maybe even reboot.
Node1 then shows Node2 as offline and the Message: "'/etc/pve/nodes/node2/pve-ssl.pem' does not exist! (500)

Checks
NTP and Timezone is set correctly
ssh root@<other-node-ip> works, but always asks for password
Clear Cache & Cookies, reload Browser
pvecm updatecerts
restarted all the Services
copied Certificates manually > Error on Node2, no Permission
Modifying /etc/corosync/corosync.conf > Error no Permission

I've tried this now with Proxmox 8.4 and 8.2

Basically the same Problem as here and many others:

Hi zusammen,

ich habe größere Probleme ein Proxmox Cluster zu erstellen.

Ausgangslage
Ich hatte vor einigen Wochen einen Proxmox Server aufgesetzt und auf Grund mangelnder Cluster Erfahrung gedacht ich könnte das Cluster im Nachhinein erstellen und weitere Nodes entsprechend hinzufügen. Als ich in den Vorbereitungen für den zweiten Node war, hatte ich leichtfertig das Cluster auf dem ersten Node erstellt. Dabei aber übersehen das die IP noch nicht angepasst war, dies habe ich dann nachgeholt und war der Meinung das ich auch alles entsprechend gefixt habe.
Beim hinzufügen...

What am I doing wrong?

Hi!

It seems like that the other node was not setup correctly when joining them. What is the output of pvecm status on node1? Is there anything significant in the syslog when joining the nodes? Is there any firewall setup between the nodes? What is the content of /etc/corosync/corosync.conf?

Thank you for your Reply.

I've given up, and switched to 3 physical machines. The Cluster is working now,
