SSL Inspection fails even after Intermediate CA imported

I have imported the intermediate CA, from 'Sectigo RSA Domain Validation Secure Server CA' and root CA 'USERTrust RSA Certification Authority' is already there on firewall default, but still outbound decryption fails.

This is a known issue with the COMODO (now Sectigo) and some RSA certs

 

Details and work-arounds can be found here:

Also, I think this may be a "fix" in the latest PANOS: PAN-148068

 

PAN-148068
Fixed an issue where SSL connections were blocked if you enabled decryption with the option to block sessions that have expired certificates. This issue included servers that sent an expired AddTrust certificate authority (CA) in the certificate chain.
