IPhone app network connection issue?

I have this app on my iPhone that WON'T stop saying to check my network connection when the connection is perfectly fine, does anyone know what up with it?

Maybe if you mentioned which app if it's only one app having the problem? Try deleting and reinstalling it.

  • Why do i need a network connection to play music on my iphone 6s? I tried to play a song with the default music app and it told me since I wasn't connected to Wi-Fi I would need to connect to the phones data. On an android locally stored music doesn't require data or Wi-Fi to play. So how come I can't play music on my iPhone without eating my data?
  • Set up a new iPhone 4S but no network connection? I've just got a new iPhone 4S and I've set it all up but my phone doesn't have network connection when it should have as all my family are on the same network and they all have connection. Is there anything I should have done? I remember on my old iPhone I had to insert my number somewhere but I couldn't remember where? Can anybody help me with this?
  • Net connection issue with my iphone? I have a broadband connection in my home with D Link Dir 816 Wi-Fi router. The problem i'm facing is that when i browse on my laptop with windows 10 i don't face any issue but when i use my iphone on the same network the internet connectivity drops after some time. Then after some more time ( typically after 30-45 minutes) it again has net connection on my iphone. I'm totally confused about this issue. I also have tried with different router of tp-link.
