If there was backup data but none of the Proxmox VE nodes reported a timezone, the Proxmox VE special agent crashed with StopIteration. All services of the monitored Proxmox VE hosts then went stale.

The agent now interprets the backup start times as UTC in this case. If the nodes run in another timezone, the backup age shown by the Proxmox VE VM Backup Status service can be off by that offset.
