Ignore Expired Certificate - SSL-Decryption

Hi!

An important website of a company I am working with is using a certificate, that just expired. Now, all of my users are getting expiration-warnings.

I need a fast workaround and wanted to let the Fortigate do full SSL-Decryption and to let it accept Untrusted Certs, etc.

--> New Decryption-profile with "Untrusted Certificate - Allow" and "Allow Invalid SSL Vertificates"

The problem does still persist - the expiration-date seems to pass.

Is there any possibility to "manipulate" this date within the Fortigate?

Thank you for your help!

Regards
