@DaxVC,

I would verify that the firewall can reach the ocsp verification source. It may be that you simply don't have a rule in place for the mangement interface to check this, however you can check it due to a policy being created to allow you to browse to that source. I would also double check what your timeout is and verify that you have it set so that the firewall actually has enough time to fetch the status.

There is a FW rule active which allows http access to the CRL server.

In the wireshark captures is the OCSP responseStatus: unauthorized (6)

I found some articles referring to the NONCE setting on the AD server, but this option is enabled..

@DaxVC,

So what certificate are you actually trying to reach out too, and is it a CRL server that you manage or not? If you are recieving an unauthroized response status then the SSLMGR will give you these responses. This is expected and you aren't getting access to the CRL and therefore you aren't able to verify that the certificate is actually still valid.
