[Update] Found a workaround with
but still wondering why it didn't come up in the UI 
New to Proxmox VE
Background info: Proxmox VE 9.0.5. Couple of days ago, I did a reboot of this node which didn't go well. For some reason the network didn't came up and I had to connect a display and cable. Was a complete disaster as the node was hosting my network DHCP server (Pi-Hole) ! systemctl showed pve-cluster.service was not running , /etc/hosts was bad, ... Long story short, I managed with the help of Claude and ChatGPT to get the Pi-Hole LXC back, and then further restore all VMs and LXCs.
But I guess all this fiddling left some leftovers... I now want to create a cluster but the dropdown list to select a network is empty. What is wrong here ?

TIA
Bash:
pvecm create cluster-name --link0 192.168.2.20
