I’ve HA runnning on a RBPI 4 with an M2 SSD connected to it via USB.
It ran smoothly for over a year.
Last week Sunday, it became unreachable and also (partly) unresponsive:
- Web interface is not accessible anymore
- Automations do not trigger anymore
- (some?) add-ons keep on working (like MQTT, because I can verify that from outside HA)
- I can still ping the device
After rebooting, I can access the web interface for ~10 seconds and then it doesn’t respond anymore (it times out after several minutes waiting).
Last week, I tried rebooting it several times without succes. Until Friday evening, after a reboot everything seemed totally fine again. I have even upgraded it to the latest HA version without any issue. Saturday it worked fine as well.
And then Sunday again, since yesterday it shows the same behaviour as last week.
- Web interface is not accessible anymore
- Automations do not trigger anymore
- (some?) add-ons keep on working (like MQTT, because I can verify that from outside HA)
- I can still ping the device
I have no clue for this. Where should I look for? I don’t have automations running (only) on Sunday. Add-ons do not update automatically.
What can I do to get HA up and running again and how can I find out what’s going wrong?
