Atag one app fails to pair

Sorry I have to ask, but my crystal ball is having some issues today:

  • Are you getting any errors? If yes: what are they, exactly?
  • Does the device still work with its official iOS/Android app?
  • Has anything changed in your home network/setup recently?
  • Have you read the official forum thread?
  • Why are you not posting your question in the aforementioned thread?
