Suddenly the URL times out to home assistant we gui, same with android app.

I’m running HASS on an virtual box in windows 11, and tried directly to add a new fresh Debian Virtualbox, but ended up with same result without changing any settings.

According to the observer URL everything is fine, but it seems the heat pump logic isn’t running.

According to home-assistant.log.1 it seems there is an issue with

“could not parse Json content in core.entity_registry”

Any ideas? Due to above issue should not be an issue with an fresh installation!?
