Hi, I’m using hassio on proxmox. Today I found it not responsive when I got back from work. Restarted the vm and now I get this error over and over again! What’s happening?? Thank you

In a previous life as a system administrator I learned to never accept a warning or error in logfiles for granted. I also encounter the message

WARNING (MainThread) [supervisor.misc.tasks] Watchdog/Application found a problem with observer plugin!

So, does anyone has a suggestion where to look for more info/logs for either the Watchdog/app of the observer plugin .

Thanks in advance
