YouTube app always says "No Network Connection" on Apple TV 4

Hi,

We were a happy family with YouTube working fine on our Apple TV (4th gen) for a while.

One fine day, the app stopped working and has been saying "No Network Connection - Please check your network connection and try again". The network seems to be fine because all other apps that use internet just work fine. I tried so many things but nothing works. Below are some of the things that I tried.

1. Removed WiFi connections and tried connecting again.
2. Closed the app and restarted it.
3. Deleted the app and reinstalled again.
4. Restarted Apple TV several times
5. Reset the Apple TV and installed the app again.

Nothing works! I tried searching online to see if anyone else had similar issue. I see that several people have different kinds of issues with YouTube, but no one seems to have the same problem as I do. Its so annoying that I couldn't find a way out of this problem. Our Apple TV is of no use if we cant play YouTube on it.

Can anyone please help me out with a fix for this problem.

Thanks,

Yaser
