This error typically occurs when the Apple TV is having trouble connecting to PBS or another app on the Apple TV. Please try the following:

 

Test the Apple TV Connection:

  1. From the main Apple TV menu, navigate to Settings.
  2. Select General.
  3. Select Network.
  4. Select Test Network.
  5. Select OK.
  6. Select Yes.
  7. Select the download speed you expect from your internet connection.


If the connection test fails, see Apple's support site for help troubleshooting your Apple TV's connection to your home network. If the test succeeds, continue on to the next step.

Or you can try powercycling your Apple TV:

  1. Unplug your Apple TV and the TV it's connected to for at least 1 minute.
  2. Plug both devices back in.
  3. Turn both devices back on.
  4. Try PBS again.



You can also try resetting your home network by turning off your router/modem, waiting a few minutes, and then turning back on.
