No internet connection. Check your internet connection as described in the product documentation.

I have below information when trying to register/activate the serial number:

"No internet connection. Check your internet connection as described in the product documentation."

While interface B has either static or DHCP assigned IP, and I can ping 8.8.8.8 from the console of the XG - so there is internet connection.

Initioally i have raised this issue in this topic:
