Description This article discusses an issue where access to URLs/IPs listed in the imported Threat feed gets blocked by FortiGate after rebooting the FortiGate which does not have a disk.
Scope FortiGate v7.2.8, v7.4.4.
Solution

After restarting a FortiGate that does not have a disk, connections to URLs/IP addresses in the imported Threat feed list are blocked by FortiGate.
The Threat feed gets updated immediately post-restart but takes about 30 minutes to fully load, as indicated in the system event logs below

In the forticron debugs, no output is observed during the feed loading process, but the following debug messages appear only after approximately 30 minutes.

This issue has been resolved in v7.4.8 and v7.6.1.

Workaround:
Restart the wad process. Sessions handled by the WAD daemon(proxy inspection) may be terminated, causing momentary disruption when the daemon is restarted: Technical Tip: How to restart the WAD process
