Cannot stream premium channels, get connect to home wifi to watch

Ever since I did a routine update on my macpro, I cannot stream premium channels.  It says "connect to home wifi to watch".  Well duhhh, I'm on my home wifi.  Other channels that I previously streamed say "you must subscribe to view this content".  All I can stream are the basic channels, which are the same channels I could get with an antenna.

I see that several others have had this same issue, but I can't find a posted solution.  The experts seem to prefer to share their knowledge by private message.  Does anyone have a solution for this that they're willing to share?

Thanks,
