Xfinity Streaming on computer Chrome just 3 dots

My streaming through chrome on my computer was working a few nights ago.  Last night when I clicked on link from google to go to xfinity stream, the normal 3 dots show up on middle of screen as usual.  But instead of loading it just stays on the three dots.  I have tried clearing cache.  Doesnt work.  Is there something that happened 2 days ago?  Any idea how I can get it back to working?
