UNABLE TO ACCESS CONTENT ON XFINITY STREAM WITH NOWTV XUMO BOXES

Worked for a little bit today when I turned it on a couple hours ago but now none of them are working.  I can access the XFINITY STREAM APP but every time I select a channel it just stay stuck loading until I get a black screen saying:

"This Video Cannot Be Played

We've run into a problem while streaming

(Error TVAPP-00148)" 

XFINITY STREAM is also unaccesible through the website, so it does seem to be an XFINITY STREAM issue.
