We are sorry you don’t have access to Xfinity tv

Xfinity stream app was working fine now it wants me to sign in. I sign in it says sorry you don’t have access to Xfinity TV. Even though it works fine on my upstairs TV. I have uninstalled and reinstalled the Xfinity stream application a dozen times with the same results. The is on an LG new TV using WiFi. Tv is mounted on wall so can’t unplug. I don’t see a way to force stop or clear the app cache. For now I will leave it uninstalled and TV off overnight
