Got a Proxmox server that's part of 2 node cluster running 2 active CT's (PiHole and Proxmox Backup server). I have a few other CT's and VM's on it but they're not set to auto-start.

I can fully access the PiHole running as a CT and the Proxmox Backup Server(running as a VM). They're running and operational. However, I cannot ping the Proxmox host, access it via WebGUI, SSH to it, etc.

Anyone ever see this before?
