Halo channel won’t work

Halo channel won’t let me watch halo nightfall any thing els I can watch, but not halo nightfall it will play for a good four or five seconds then puts a message on screen saying to retry the video or go to guide and I have tried it a good 50 times and still the same result so is there any thing that can help it. Also I did redeem a code for halo night fall so I do have and own it.

That happened with a friend of mine as well. I believe that it was probably a connection issues/bad stream for nightfall but it should be fixed by now.
