Xfinity To-Go says I need a subscription for local channels ABC, NBC, CBS

I am Xfinity internet and TV subscriber through my condo association (entire complex commercial account).  I use TO-GO service on a compter using Firefox browser a lot since I travel.  Until yesterday I was able to view CBS, ABC, and NBC (though NBC is flakey) using TO-GO service.  Yesterday ABC and CBS are the To-Go list, but if I click it says I need a Subscription.   I have a subscription.  What changed since yesterday?  How do I fix?  Thank you
