Apple TV + on my TV will not connect all of a sudden.

It keeps offering me a free trial for 7 days. I have an active subscription verified by Apple Support. I tried to sign in in settings on my Apple App and all it does is spin. Apple TV works fine on my iPhone. Apple Support could not help and told me to call cox. I called Cox and the person I spoke to said he was aware of the problem and had several calls on it and said A Tech would need to come out and do something to the contour box. Unfortunately no one showed for the appt he told me about because the guy never actually scheduled it. I’ve rescheduled but this second guy had no knowledge of this issue. Anyone else have this issue??? Ive rebooted several times, disconnected from wall and from contour box several times.
