Netflix no longer streaming

I have the same problem, I'm still trying to figures it out. I got T-mobile Home internet two days ago. I'm  not able to "Launch" Netflix app. When I Launch the app, it buffer on the logo for awhile and said " can't connect to Netflix". I tired everything to resolve it. My Netflix works on my iphone but not on ( my fireTV, xboxOne S, and Goolge Hub). I tired using a router to see if it help and it doesn't .  THE ONE WAY I COULD STREAM NETFLIX IS TO LAUNCH THE APP USING MY HOTSPOT from my phone. Then, switched back to T-mobile Home internet to stream videos. If i turn off my tv, and try to launch the app it won't work. I have to go through my phone hotspot again. It's so weird. Help!! I don't want to do it everytime i turn off my tv
