Solved
After a week of trying to make my beryl work with my Xfinity xb8 router I gave up.
Xfinity xb8 modem wont consistently recognize the beryl as connected and makes it very difficult to port forward 51820 or 1194. Switching between medium and high security it eventually stuck. This made the connection to the beryl possible from my clients however the connection was very unreliable.
Switched to Netgear modem and router and everything seems to be working without issue. Note use the Netgear app to setup router/modem if it supported. Also Xfinity charges you an extra fee for unlimited Internet if you get your own device.
I still see errors for xxxxx.glddns.com not working (yet to investigate) but the beryl is working now
