Xfinity Stream issues on Roku

Hi. The Xfinity Stream app that's on my Roku device, which is connected to a Samsung TV, says that I am not on my home network. I cannot watch live TV nor view 'favorite channels'. 

I verified that my Roku is connected to my home network. My phone, which is on the same network, can stream Xfinity without any issues and I have no issues using Netflix or other apps on the Roku device. I have restarted my gateway, uninstalled then reinstalled the Xfinity Stream app, but it still is giving me the same error. I have multiple Xfinity accounts.  I wonder if somehow the affected address isn't my primary profile location. I was on a chat with a tier one rep last PM but he couldn't resolve it. Someone was supposed to call me today but they never did.
