Can't push policy from FMG to FGT. Certificate Errors

[vk123]

Hello everyone,

I'm trying to create a small VM lab based on a FMG and a few FGT. I did set up every VM correctly but I'm facing an issue whenever I add a Fortigate to the FortiManager and try to push a new policy package to the FGT. Looks like it's a problem about certificates.

Install History:

HUB-1 80% 2020-07-02 05:12:34:fgfm install state: prepare to post-checksum HUB-1 90% 2020-07-02 05:12:40:post-checksum state: start verification HUB-1 95% 2020-07-02 05:12:44:verify state: install OK/verify FAIL

I know other people have faced the same issues but still no fix for this. Any idea ?

Help is welcome.

Thanks a lot!

There are two options to fix this;

1

login to Fortimanager

Policy and Objects (Tools - Display Options - Advanced),

Object Configurations > CLI Only Objects.
Expand vpn, expand certificate, select ca.
Select and Delete the certificate that is causing the issue.

2.

If required, you can remove the certificate from each device’s configuration.
Device Manager screen,

CLI Configurations.
Expand: vpn, certificate, ca.
Select and Delete the certificate that is causing the issue.
