Receiving Error  when trying to use the Xfinity Connect app via my home WiFi connection. When I turn WiFi off and I’m on cellular connection the app works fine with no error. No problems with home WiFi connecting with anything else.
I haven’t verified yet, but I believe this is occurring because I’m using Cloudflare’s DNS (220.127.116.11) which Comcast is null routing. It seems this affects the Xfinity apps and watching TV via Xfinity stream website. Switching to Google DNS should hopefully resolve this error.
