Xfinity Stream App not Working - Not recognizing network

I just had a new cable modem/wifi router installed.  XB6.

Prior to this I had my own cable modem and used Eero as my router. 

I have a Roku TV and used the Xfinity Stream app and it worked well.

I turned the wifi router off in the XB6 and set it up in Bridge mode. So my wifi is broadcasting from the Eero.  My Roku TV recognizes the Wifi network and streams all the apps.  However the Xfinity Stream app does not recognize the Wifi network.  When I launch it I get:  'This device can only access Xfinity Stream on your in home Xfinity network.  Use the app on your smartphone, tablet, or laptop to watch on the go, any time you like."
