Roku FoxNews channel login problems

Up until about a week ago we had been using Roku to watch live streamof FoxNews on  our Roku.  The we started getting error which said the service provider is not allowing the content.  After struggling with this for few days, finally got COX to tell me our COX password needed to be re-set.  Why that was needed is a topic for another thread, but I set a new password. 

After removing the FoxNews app and re-adding it to our Roku lineup and logging in again with activation code and COX login, the FoxNew live stream worked again...until the next day.  Then it was locked again.  I had to remove it again, then log back in again.  Then the next day is was locked AGAIN.  What is going on that I have to keep logging in with with the activation code and cable provider once a day!?
