I have a TCL Roku S515 TV. I have installed the Xfinity Stream Beta app and signed in. When I go to Live TV or Browse, I get “Error getChannelMap.504”. Saved does show my recordings successfully, and I can watch saved recordings. I have logged out of the xfinity app, reinstalled the app in Roku, rebooted my tv, and rebooted my router. I still get the same 504 error. LiveTV and Browse continually give this error. How do you fix this error on Roku TVs?
