My ha that I am running on my rpi cm4 just stopped running after night and I have no idea what is the problem. I cant find it anywhere on my network and no idea what is the problem. It looks like it cant connect to network and I have no idea what is happening. I can give you some screenshots.
That’s a time sync issue. Modern auth requires clocks to be synchronized with a certain margin. This happens by syncing to an NTP server. When time is out of whack and it can’t sync you get this… Does your HA machine have access to the internet? Do you run something like Ad Guard or Pi hole modifying DNS responses?

No i am not running anything else and yes it should have acces to internet but for some reason it doesn’t show up when I try listing all network devices.
