FortiGate-VM under Hyper-V, evaluation license fails + Web GUI loops at login

the token should be the 2FA that you use on Fortinet Support Portal login for the account used to activate the trial which can be set as described here

That makes sense, thank you ​@funkylicious .

Result :
 

FGVMEV6QTRV5Q68D # exec vm-license-options account-id xxxxx@xxxxx.com

FGVMEV6QTRV5Q68D # exec vm-license-options account-password xxxxx

FGVMEV6QTRV5Q68D # exec vm-license ######
This operation will reboot the system !
Do you want to continue? (y/n)y

Failed to download VM license.

FGVMEV6QTRV5Q68D #

In my Fortinet Support portal, I do see the serial number:
 

It seems like Fortinet doesn’t recognize the UUID or serial, because it cannot grab the eval license.
I have downloaded the License File through the link on the Fortinet Support Portal, then used an FTP server to “restore” it to the Fortigate-VM.
It seems to have gone “ok” since it rebooted after.

However, status is still the same after that reboot.

Running the command 
diagnose debug vm-print-license

returns this
SerialNumber: FGVMEV6QTRV5Q68D

This is getting weirder. See the screenshot, it shows the SSH access to the FortiGate-VM on the left, and the Hyper-V console to the same VM on the right.

I’m thinking maybe there’s a similar problem with the HTTPS access?

I have the exact same results between console access via Hyper-V and SSH (Putty). 
Seems anything you try to access via the IP interface, it logs out and doesn't see the valid license.
Mostly https access, this even happens if you load the *.lic file from your FortiCloud account via TFTP server. 
Same results, doesn't update the license via IP access/permitted.

I noticed that if I login to HTTPS, I still get the loopback to the login screen, but I tried hitting the Back button of the browser.
Now I see a dashboard, but with all widgets in a “loading” state, for about 10 seconds, then back to login screen with the message “Your session has expired”.
 

I have the same problem. 

I have the same problem logging in. Has anyone managed to solve it?
