Had a similar problem with my xb1, but i have 2 xb1's , one was connected wireless, the other wired. The wireless worked fine, the problem was with the wired connection. swapped it to wireless and have had no problems since. It was not a fault with the connection itself, because other apps such as Amazon Prime worked perfectly on the wired connection. For whatever reason, the Now TV app doesn't like a wired connection to my xbox.
Hope this helps
Having this issue as well.
Come home to watch GoT. Went to launch NowTV and it said it needed updating, it updated now it won't launch and gives error "0x8027025a"
Reinstalled it, rebooted it, rebooted all internet related equipment.
ALL other apps are working perfectly fine.

Same club as others, XBox app needed update and now it is completely borked, does no one do testing on these updates before applying them it's obvious that it has broken the XBox one app.
