Hello Nelson A, What is the PAN OS version running on your firewall...? Have you seen any error/warning messages on SYSTEM logs..? Which Devices in an HA Pair Can Connect to the PAN-DB Cloud? The Active device will not regularly sync the cache over to the Passive. Since the Passive device is not getting any traffic, it will also not do any cloud lookups on its own for URLs. Every 8 hrs or so, the Active device will make a backup of its MP cache, and that will get synced to the Passive device. If you use the CLI command on the Passive device to download a seed database, it will do that as well. So, basically when the Passive becomes active and do a URL lookup it will then update its version too. Thanks
