Can't connect to Home Assistant (local IP, homeassistant.local...)

Hi!

I am running last available version of HAOS in a NUC.

Everything was working OK until I was not able to connect to Home Assistant via iOS app. Error showed was “Response status code was unacceptable: 500. Error Code: Alamofire.AFError 9”.

I was able to connect to Home Assistant at that point with a browser within my local network, so I rebooted the host from Home Assistant and then was not able to connect neither from the iOS app, nor from my computer via browser.

Browser error I got is: “ERR_CONNECTION_REFUSED”.

Tried “http”, “https”, local_ip:8123, homeassistant.local:8123 combinations without success…

I connected a monitor to the NUC. In the screen I can see the welcome Home Assistant banner with “Waiting for CLI to be ready” sentence above the banner. Don’t know if this is relevant. Attached picture of the screen for your information.

I tried Observer URL and got three green messages:

|Supervisor:|Connected|
|Supported:|Supported|
|Healthy:|Healthy|

I am running OS 9.3 and Core 2022.11.2

Any help will be highly appreciated.

Solved after restarting the router.
