Sky Go error when trying to manage devices

I have Sky Stream and Sky Go. Both work fine, and Sky Go allows me to download and stream the services that I subscribe to.

If I go to settings in Sky Go, then 'Manage your devices' then select select 'Manage' on the 'Streaming TV' device, I get the error attached. Any ideas? My Sky Go device (Apple iPhone) and Sky Stream devices are on the same local notwork.
