These error codes can appear for different reasons depending on the player, so there is not one universal meaning.

Try:

  1. Confirm your subscription is active.
  2. Verify the Server URL, username and password.
  3. Restart the IPTV player.
  4. Clear the app cache.
  5. Delete and re-add the playlist using Xtream Codes.
  6. Try another compatible IPTV player.

If the error appears only on one channel, send support the exact channel name.
