If an external CA is used that does not provide Certificate Revocation List (CRL) information, you must disable CRL on the System Manager instance to which Avaya Breeze® platform is registered. On the Security > Configuration > Security Configuration page, set the Certification Recovation Validation field to NONE.

If an outgoing HTTP proxy is set up, CRL download might not work. In this case, you must download the CRL list and then update it on System Manager at Home > Services > Security > Configuration > CRL Download.
