Remarks

This event is fired when a CRL that is needed to validate Cert is not found at any of the available locations. If you have access to the missing CRL, please add it to the known_cr_ls collection to make it available to the validator.

When this event fires, the current_certificate and current_ca_certificate properties are assigned with the certificate being validated and its issuer certificate.
