supervisor state in info tab is healthy

but in the observer is unhealthy and Unsupported

Have you tried downgrading to the stable release of HA OS and the supervisor?

You are running beta versions.

let me try that
Edit:
tried to leave beta
this happened

Edit 2:
tried from command line
➜ ~ ha supervisor update --version 2022.4.6
Processing… Done.

Post "http://supervisor/supervisor/update": dial tcp 172.30.32.2:80: connect: connection refused

Reinstalling and using a stable release solved it.

Devil has returned, upgraded to 2022.4.7 and the same issue again. can’t access the supervisor.

when I try to reboot host from ssh

➜  ~ ha host reboot
Error: System is not ready with state: shutdown

``

found this error in esphome logs

13:28:04	[W]	[api.connection:083]	
ESPHome Logs 2022.4.0 (::FFFF:C0A8:12F6): Connection closed
13:28:05	[W]	[api.connection:083]	
Home Assistant 2022.4.6 (::FFFF:C0A8:12F6): Connection closed

Did you ever find a solution to this?
I am regularly experiencing the same issue.

reinstalled HA and updated it was resolved for me.
