Security Intelligence feed downloads may fail when network traffic between the SRX device and the feed server is blocked or dropped by an intermediate firewall or security device.

Security Intelligence feed updates fail with a timeout error similar to:

Download manifest failed <connection error: Timeout was reached> [28][0]

Security Intelligence trace logs show repeated attempts to fetch the manifest file without receiving a response:

Fetch https://<feed-server>/api/v1/manifest.xml?device=<id> from server, try 1 times

Fetch https://<feed-server>/api/v1/manifest.xml?device=<id> from server, try 2 times

Fetch https://<feed-server>/api/v1/manifest.xml?device=<id> from server, try 3 times

Verify end-to-end connectivity between the SRX device and the configured Security Intelligence feed server.

If trace logs show repeated fetch attempts with timeout errors and no response from the server, inspect any firewalls, security devices, or network policies in the traffic path. Ensure that the connection is not being dropped or blocked
