FortiManager -- cannot upgrade FortiGate firmware after upgrading to 7.0.5/7.0.6

[anttikoskenvoima]

After upgrading our FortiManager to 7.0.5 (and now to 7.0.6), we are unable to upgrade any FortiGates. Every attempt to upgrade Firmware ends with the status "no valid FMWR license" . The FortiGate upgrade we attempting is e.g. a 40F (and a 60F), from 6.4.11 to 6.4.12.

We have checked the licences, and there are no issues with them. We have tried upgrading from FortiGuard and from a local image. We always end up at "no valid FMWR license" and the update fails.

Updating the FortiGate from its local UI does work without issues

Has anyone else had similar issues? Any tips?

Yes, discussed, but the solution does not work.
