Opening Hulu App Error

I'm getting this message while trying to open my Hulu App: "Give Us A few Minutes. We’re having trouble opening this app. Please give us a few minutes then try again. APPS-04154."  Prior to this past weekend, I wasn't having any issues.  This is only happening on one of the TV boxes (the main box).  I've tried everything that was suggested.  Rebooted modem, restarted box, more than once.  Nothing is helping.
