I haven’t had the iOS app running in a while as it only connects on Wi-fi. I’m pretty sure, although I’ll have to check, that it works when I’m on Wi-fi outside of my network.
This is still happening to me…
iOS app works on Wi-fi (even outside of network) but doesn’t over cellular.
At the same time, just going to a web browser over cellular does work! So it’s the app being freaky rather than any network setup I have .
My guess is your cellular provider is blocking or modifying the connection. There’s a new log export function in the 2.0 beta (coming soon) which will shed more light for you and me.
