I get the error only when I connect from my local network wifi. If I use my smartphone from a remote location everything works fine.
Tado does not support WiFi. You need to connect the bridge to your internet router using a cable.
The bridge is connected to the router using a cable. As I said everything works fine when I connect to my Tado from outside my lan (i.e. Mobile networks) when I try to connect from inside my network I get the connection error.
I get the same error repeatedly. Keep hitting retry and eventually it works - can replicate on multiple phones. There's no network issue, it's Tado.
Are you both using the same model phone perchance?
Your phone just needs access to the internet, so it can reach the tado backend. Nothing special about that. I don’t see why it would be different from your local network or another network. So it must be some connectivity thing on your local network.
Funny however that your bridge can reach the tado backend through the same router?
I'm seeing the same problem, the app and web don't work when on my local wifi, if I disable wifi and use 4g it works. Doesn't make much sense really.
