As all Fibaro services are working,   Please login or register to see this spoiler.   i took a deeper look. It looks like the Fibaro changelog server is down, so the home center update page can't load the firmware changelog, therefore error 500. This will be of course error as well on Yubii, HC3L, HCL and HC2, as they all using the same firmware changelog server.   @m.roszak Fibaro (or the provider?) can you forward this info to your IT?     From user perspective
