Troubleshoot Signature Delivery
Gateway AntiVirus, IntelligentAV, Application Control, Data Loss Prevention, Botnet Detection, and the Intrusion Prevention Service download signature updates from the same update server. You must keep your signature database updated to secure your network from new threats.
To download signature updates, the Firebox device connects to services.watchguard.com and downloads from cdn.watchguard.com. If your signature update server configuration is correct and the connection is not working, consider these possible reasons for the failed connection.
Unresolved DNS Name
Make sure your device is able to resolve DNS names, including:
Blocked by Firewall
Make sure the HTTP connection to cdn.watchguard.com is not blocked by another Firebox or firewall.
Download Timed Out
Make sure the link speed to cdn.watchguard.com is fast enough to download the file. The download can expire due to slow download speeds.

In the case of an ongoing issue, it may be necessary to provide Technical Support with debug level logs for the signature update service. Turn on debug level logs and rerun the manual signature update.
