A duplicate license error means that FortiGuard server has detected another FortiAnalyzer-VM that has applied the same license. You might need to check if you have other devices that is using this license. This can be checked through the Serial Number of the device as the Serial Number is binded to the product license.
If you plan to reuse your license, then you will need to completely decommission or power off the old VM.
If you have found a solution, please like and mark it as solved to make it easily accessible for everyone.
I am using the trial FAZ and FAZ seems to be in an endless loop where it cycles between "Trial license" and "VM license is invalid because license is duplicated." When I attempt to login, FAZ alternates with normal login or presents the initial setup dialog. I have only registered/licensed the VM once and Forticloud shows just the one asset. Any idea how to fix this? What is going wrong?
