runlevel (to lvl 5) 4

runlevel? can you post the full

pveversion -v

output and check with

systemctl status

what service run? to get a bit of a better overview of your server.
Also the last messages from

journalctl -b-1

(journal from the last boot) if you scroll down would be interesting.

Additional, do you have a cleaning service, or someone else which could accidentally hit some power/reset buttons?

I have been attach output command,
journalctl -b-1 only show "Specifying boot ID has no effect, no persistent journal was found"

can I disable power/reset buttons on user interface ?
