Xfinity Stream App not working

Has anyone noticed that Xfinity Stream app no longer works behind a router.  I have a Xfinity Cable Modem and Meraki Firewall behind it.  All I know since Feb 9th.  I have not been able to use Xfinity Stream on my Roku devices, computer, or Tablets.  I can only use them if I connect directly to the Xfinity router or Xfinity Wifi.  I have my own Meraki AP and router behind the Xfinity Modem.  What has changed?  Even though my Meraki has its own subnet it is plugged into the Xfinity Router so all the traffic should be coming from my Xfinity IP address
