Re: Xfinity stream app does not work

Our one and only mobile android device (Tablet) is working fine with everything available on the Xfinity Stream app via Wifi.  

However, just recently our ethernet connected Windows PC (w/Firefox browser plus the latest Flash on our 1Gig HSI Tier) has started to generate a "Try Again" message each time we try to view Live, OnDemand, or Clould DVR content using our PC via the Online Xfinity Portal ... (Except for NBC TVGO, which strangely continues to works fine Live) .

Here is message now poping up on our ethernet connected PC (except for NBC TVGO Live as mentioned above):

                              "It looks like your device is offline"

"Once your Internet connection is restored, your video will resume automatically."

                                            "Try Again"

Have tried things with all 4 of our existing user account names, plus tried the "create a new account suggestion" offered previously in another thread by @Rustyben to no avail.  FWIW, we've had the same default username and 3 secondary accounts for the last 17 or 18 years. Also rebooted our Cable Modem and Router.

Not sure if I've posted in the right place ... Is this known recent issue?
