Bridge can't connect to WiFi after changing network

I recently changed ISP and tried to setup everything again, as this specific ISP has a cursed features that forces its name onto the SSID, forcing to reconnect everything. With the Bridge I’m having issues, though.

I set the Bridge to Mantainance mode, it starts flashing, and then I try to connect with the app. The first time it’s ALWAYS an error message, then it tries again and it connects, but showing no reach to the server.

I also tried to restore it to factory condictions and to leave it 24 hours on the new network. Nothing. Is there something I haven’t tried that I should?
