Sophos XG for VMware: Unable to register he serial number even if the FW can ping www.sophos.com

Hello everybody,

I am new in the Sophos world.

For practising I installed Sophos XG for VMware 18.5.1 on my VMware Worstation 15.1.

When I access the Sophos XG from a virtual PC using https://<ip address>:4444 the basic

setup procedure starts. I copy&paste the the serial number into the field 'I have an existing serial number'

and click <continue>. After some seconds I get the browser message: 

We can’t connect to the server at www.sophos.com.

I can ping www.sophos.com from the Sophos XG command line without problems.

What can I do to get the registration of the serial number working?

Every hint is welcome.



Thanks a lot!
