What box, or Kodi addon are you getting these errors on? In the service subforums, just saying you are down or have errors is not helpful, and probably most best to ask for help for your device or kodi setup.
A quick way to check if the service is up or down for you is the put your portal url (11.iptvprivateservice.tv) into a browser and seeing the blue screen trying to login. If you don't see that, either your connection, the internet routing or the server is down. If you do see that blue screen, it means that the server doesn't recognize your connection from your client, so you need to check your settings, then do an IPTV Reset.
