When I debug with Devtools I see a 403 error when going to http://umbrel.local:8240/api/up page with response: Forbidden - origin invalid

Anyone any idea?

Hello, you are not the only one with this problem. today I decided to try UmbrelOS for the first time after CasaOS and faced exactly the same problem as yours, but alas I don’t know the solution.

I see they released an update to revert to a previous version.
