Fetch dosen't work only mobile platform in hosted test

  1. Run your serverURL against SSLLabs SSL Server Test (Powered by Qualys SSL Labs) to test/check that it can support mobiles calling it, it might throw up a bad cipher configuration
  2. Change $('#log').append(err); to $('#log').append(err.message); or $('#log').append(JSON.stringify(err)); to attempt to log more inforrmation. just logging err might not return anything useful to work with. Or return/append all three
  3. Load up some test code in a browser on your phone instead, outside the TwitchApp and use the relevant debugging tools for that mobile to invetigate the issue further.

I’m assuming $ is jQuery?
