Same thing happened here.
Fox Business is working fine.
I have Comcast/Infinity as my supplier. Occasionally I lose service and a message pops up telling me that my equipment is not authorized to receive this channel. It is not channel specific, just whatever channel I’m watching at the time. The message directs me to call a number which I ignore. After a brief while my normal service resumes. I think this is some kind of a hack and scam trying to get a credit card number or sell unwanted services.
Here we go again. Day 2 and no Fox & Friends or Fox Business. Are you having the same issue?
