The warning Pop Up Message is like the screen shot below. You may get this error and unable to watch any movies or tv shows on your iPad. Before proceeding this fix you have to make sure you are corrected all other possible errors like weak WiFi signal, Low Connection Speed, etc.
See above for the same popup message that I got on my iPad. Once you get the above message, go to your iPad Setting >; Wi-Fi >; Your WiFi >; HTTP Proxy change from AUTO to OFF.
