When running Threat Insight and/or ADP on the Grid, to download the latest module updates and whitelist updates or ADP udpates , the Grid Master needs to resolve and access https://ts.infoblox.com on tcp-443. You may need to configure the proxy settings in the Grid and you may need to disable TLS inspection on the proxy.

For Threat Insight, only the Grid Master receives module and whitelist set updates. Grid member receives these updates through standard Grid replication from the Grid Master. Module and whitelist data is only replicated to Grid members that have the threat analytics service enabled (an RPZ license is required to start this service on the members). The appliance uses the port 443 (HTTPS) for downloading the module set and whitelist data updates.

Note: The scheduled time does not indicate the exact time for the download. Downloads occur during the mid-point during a 30-minute time frame. Therefore, the actual download can happen 15 minutes before or after the scheduled time.
