I recently acuired a secondhand NUC8I5BEH and installed proxmox on it. But it randomly is unreachable from my LAN. There are no errors in syslog. When I connect a monitor there is no signal. So the NUC seems crashed. The fan is spinning and the LAN lights are on. It’s not viewable on my unifi controller and it’s not pingable. Where can I start looking for the problem?

Try a live Proxmox USB, it’s what I did when my machine went unresponsive. Allowed me to look through the logs of the OS when it hadn’t booted to find out what went wrong.
For me it was that I had put my USB HDDs in via Fstab and one had died, which made Proxmox unbootable until I hashtagged the lines out in fstab.
