I'm getting this problem, starting 8/27/19. At first I thought it was only on my end because it was only affecting my 4k fire stick, the older model worked fine all day but tonight I am getting the error message on that one too. I tried the usual, logged out and back in, cleared cache, data, reinstall, restart, even did a factory reset on the 4k stick. No luck. I can play host intros but not movies or live broadcast. Tried two tvs, nothing. Other apps working fine. Frontier is service provider. Anyone able to play movies right now?
