registration of evaluation license
I am new to FortiGate, i am trying to setup evaluation license on a VM for training purpose, im facing a problem in accessing the GUI, i have registered the license once and it was working good and then it did not work on the next day , i have reinstalled the VM and deleted the license from my fortiCloud account, after that i always receive this message when i try to register the license “Error in downloading license : Invalid serial number “ Â

i’ve tried to register it manually on forticloud but not worked, any advise ?
