Apps on Apple TV won't authenticate

So, I have been able to authenticate many apps on my Apple TV. Netflix, Showtime Anytime, ABC, and HBO GO all work fine. I have DirecTV. Now, all the sudden, I am unable to get any other apps to work. I've tried Fox, A&E, and FX and none will work. I have restarted my Apple TV and my router and had no luck. I am trying to avoid doing a factory reset because I am worried then none of my apps will work.
