Can't shutdown or reboot my System

When I try to shutdown my System (or reboot), I get the following error:
systemd-journald[462] Failed to send WATCHDOG=1 notification message: Connection refused.
I did not have any clue and tried the whole day to fix it. Ended up reinstalling EndeavourOS. Then I noticed it even happens with a LiveUSB Stick. I dont know what the hell to do at this point. If someone knows whats wrong with my system I would appreciate some help :slight_smile:

Have you checked the Arch Forums for clues? I came across this, perhaps it will help:
