The application needs to be able to contact at least one of the CRL Distribution Points (CDP) listed in the Details tab of the server's certificate, and also the CRL for any subordinate CA servers (root CA generally will not have a CRL).

Typically there will be at least one http URL so will need to contact over tcp port 80 to that URL (normally should not be on an https link for CRL validation).  It is also somewhat common to have an LDAP location and occasionally a local file location as a backup option for manual downloads.  These CDP locations are configured on the issuing CA server.

If it is an internal CA, then the CRL may not be advertised to a publicly accessible URL in the CDP.

If this is your company's CA and the CDP location is not published to a place that you can access, you may be able to get them to update the CA server to include another CDP location for you.  In most organizations this will be the Enterprise Administrator, although larger organizations may have a delegated PKI team.
