I've downloaded the app and registered. When I then open app to try to pair the box usually it doesn't find the box. I've tried entering the IP address and I get the message "Connection has failed". A couple of times I do see the box in the app and clicking it I get the same message. I'm connected to the same Wi-Fi network as the iPhone/iPad (Both fail to pair). I've used iPlayer to confirm I have network connectivity.
Any ideas to try please?
