FortiGate VM lost Serial Number after uploading Evaluation license

Hi,

I am struggling with Fortigate VM evaluation license upgrade. My FortiGate VM had been deleted, it worked just fine, and I imported it from my backup. At first it seemed fine. I had correct serial number, I was able to reach for an evaluation license to the forticloud asset. Devcie has downloaded it succesfully and rebooted. That's were the issue begins. After reboot, name of the device has changed to Serial Number and the SN disapeared leaving VM with a wrong one. I did factory rest and it allowed me to restore proper SN for my device but issue is beeing repeated everytime I try to get the Eval License. Any idea where is the problem?

 

Before license update.

After reboot hostname is changed to SN and SN is invalid

Many thanks!

Hi Martin,

 

I maybe found something:

 

If a FortiGate VM loses its serial number after uploading an evaluation license

  1. Verify License File: Ensure that the correct evaluation license file is downloaded from the Fortinet Support Portal and uploaded to the FortiGate VM.
  2. Check Internet Connectivity: Confirm that the FortiGate VM has internet connectivity, as it needs to connect to the FortiGuard server for license validation.
  3. Management VDOM Configuration: If using multiple VDOMs, ensure the management VDOM has direct internet access and is not routing through other VDOMs.
  4. Reboot the VM: Sometimes, a reboot of the FortiGate VM can resolve issues related to license validation.
  5. Re-upload License: Try re-uploading the license file via the GUI to ensure it is correctly applied.
  6. Check System Status: Use the CLI command `get system status` to check the current license status and serial number.
