My home assistant crashed

So I did the latest update to home assistant Yesterday on my raspberry pi 3b+, and since then I haven’t been able to access home assistant, and it doesn’t even show up in my router when I check the connected devices page. It is connected to the router via ethernet, so it’s definately not a connection issue… I made backups on the hassio page a few days ago, but I don’t know how to restore my rapsberry pi to that backup without being able to access the web UI. Anyone have any idea how I can fix this?

Nevermind… Just unplugged it and plugged it back in… Woking now…

Classsssssic!

Hello!
I am in a similar situation.
I installed HA on a raspberry pi 4 and I’m constantly losing connection. I don’t understand if it craches but I turn the power on and off and return to normal for another 2 hours until it disappears from the network again.

Any idea?
