FortiManager Unauthorised Devices

[DT3]

We are running FortiManager 7.2 on Hyper-V. Over the weekend the host installed updates and rebooted and now on FortiManager it states the Fortigates are unauthorised.

I have read that having dynamic Mac addresses could cause this issue, but I have now set to static in Hyper-V and the issue persists after reboot - the FMG asks for its hostname, then the 2 x Fortigates say unauthorised despite being authorised prior to the reboot.

Any ideas?

Did you apply the license to the FortiManager? Also, have you register it?

[DT3]

Yes, license is applied and activated. The issue only occurred following a reboot of the Hyper-V host.

Sound like a bug to me but is better to raise a case with support to confirm.
