Proxmox server shuts down after a few minutes?

Hi,

I've been running this Proxmox server since more than a year. Yesterday I ran the updates
Code: 
apt update && apt upgrade && apt clean && apt autoremove
like every few days before shutting the server down for some electrical maintenance. I was rewiring an electrical circuit - this server and another server which is running fine (also updated before shutting down) are on the same UPS. Because of this I am sure this is not an electrical supply problem.

The server boots up without any error (wouldn't I see file system error messages if it just lost power?), launches all VMs, but after 10 - 20 minutes when I check back it's turned off. I don't know if it shuts down or turns off, and have been running

Code: 
tail -F btmp debug faillog kern.log lastlog messages

from a SSH terminal to see if anything happens but nothing there except the usual stuff:

Code: 
Jun 13 08:30:00 zen systemd[1]: Starting Proxmox VE replication runner...
Jun 13 08:30:04 zen systemd[1]: pvesr.service: Succeeded.
Jun 13 08:30:04 zen systemd[1]: Started Proxmox VE replication runner.
client_loop: send disconnect: Broken pipe

I already looked what happened when I let the machine sit in the BIOS for longer - it doesn't turn off there.

I have no idea how to figure out what is happening. How do I access the relevant logs from before the reboot? For example, on other systems there was a /var/log/dmesg - but not on Proxmox?

Any help is greatly appreciated.

Thanks!

Please always use apt full-upgrade with PVE:
full-upgrade performs the function of upgrade but will remove currently installed packages if this is needed to upgrade the system as a whole.

Anything in journalctl -b and /var/log/syslog?
