I upgraded to iOS 14 and everything went smoothly for about half a day, but then I noticed that all the hubs at home were listed offline. Even my automations outside the house did not start correctly. I soon realized that I could not access my devices outside the house at all.
I browsed all the devices and checked, all are updated to iOS 14, and Apple TVs are now updated to TVOS 14 (they were not before), but that did not solve the problems.
I tried a network reset, restarting the Apple TV device after disabling / activating the Home Hub status. Nothing works. It’s very frustrating.
Edit: All hubs are listed as “disconnected” in the home application for some reason. I don’t know how to solve this.
