Supervisor crashes all the time (Could not load the Supervisor panel!)

Installation Home Assistant OS
1

Hello,

I hope you can help me.
I run Home Assistant OS on a Raspberry Pi 4
For the last couple of days I have the issue that at some point the supervisor seems to be going down for no reason.
The Dashboard still works and for example I can still access the integrated Shelly Integration but for example all Zigbee Devices that are controlled via Zigbee2MQTT are not accessible anymore.
I also can not restart the RPI via the Interface, I need to physically unplug the power and after that it works for a while.

I am on:
Home Assistant 2023.1.1
Frontend 20230104.0 - latest

I updated the core yesterday in hopes that would resolve the issue but still the same happened today.

When I open the Addon Section I get the Message: Could not load the Supervisor panel! and some troubleshooting advice.
The observer gives me:
Supervisor: Connected
Supported: Unsupported
Healthy: Unhealthy

I also attached an excerpt from the logs where I can find the error message related to when I open the Add Ons section.

Any help would be greatly appreciated.

If anyone ever come across this issue:
within the CLI:

ha core rebuild 
ha supervisor repair

seemed to have done the trick.
My setup now runs without an issue for the last couple of days.
Thanks again for the help.

I know this is old (so apologies for necroing it) but it seems the most appropriate place to post.

I had a similar issue with a setup at a family member’s house and was scratching my head for quite a while trying to figure it out. I had constant errors when rebooting (the CLI would say the supervisor isn’t ready) and I noticed that updates for the OS and supervisor that were there in the morning had stopped displaying as if they weren’t available. The CLI also wouldn’t allow or show any updates. Because of the Could not load supervisor panel! error, it had me focused on troubleshooting this and nothing else. I also couldn’t see a supervisor entry and version in the About page, I just had this:

Core 2025.2.5
Frontend 20250221.0

Which also made me think the issue was purely the supervisor.

Oddly, the observer said all was ok:

Which it obviously wasn’t.

I tried rebooting after a ha supervisor repair without luck. But it was actually after a core rebuild as above (ha core rebuild) that did the trick, within a few seconds everything sprung back to life.

So if you have an issue with the supervisor, rebuild the core as well!
