Foxnews issues

I have xfinity cable subscription. I have a cable box on my down stairs TV. I have a firestick on the bedroom TV. I can watch Fox News on my firestick. Every time I start fox news on my Firestick I have to logout of my service provider and log back in with a code from the TV. I can be watching live fox news. It will buffer and kick me out of live TV and I have to log out and then back in with service provider again. I have never had to do this before. This just started in the last couple of months.
