Fortinet VM Evaluation license activation - 7.2.1

[ip_net_null]

I am trying to activate a Trial license for a 7.2.1 Fortigate VM - I have an active Fortinet account with FGT's under current contracts. When I try and activate the evaluation license I get the error below.  

Gui error: 

From the CLI  I see this. 

Requesting FortiCare Trial license, proxy:(null)

The unit has unrestricted access to the internet (DNS etc) here is the port config for the interface I am using

I encountered the same issue. My WAN configuration was set to DHCP. After manually configuring the DNS and adding a static route, I relaunched the evaluation registration, and it worked successfully.
