For the dynamic real-time rating (DRTR) to function, the following requirements must be met:
- DNS is able to resolve webpulse.es.bluecoat.com (SGOS 6.6.x) or sp.cwfservice.net (SGOS 6.5.x).
- Internet communication to the previous URL must not be interrupted. Ensure that the firewall allows access to the domain by performing a PCAP from the appliance.
If these requirements are met and the issue still occurs, troubleshoot the DRTR service on the appliance. See the Resolution
