Tv app

I have had a error code 160 message when trying to run app. It has happened several times. I try to turn iPad on off, recycle the wifi and router by pulling power, and also wifi on iPad. Nothing seems to work. Then magically it works later in day. Can you give me a idea on what I should do. I use the app for about two hours every day in morning to watch news. So I don't wake anyone in house.
