298001 - Connection Timed Out

Agent error code #298001 indicates that the agent attempted to connect to a firewall to refresh an external object (such as an External Dynamic List or dynamic group), but the connection timed out before a response was received.

This error specifically occurs when the agent can reach the network but does not receive a response from the firewall within the expected time. Common causes include:

  • The firewall is under heavy load and unable to respond in time
  • Network latency between the agent and firewall is too high
  • A firewall or network device along the path is silently dropping packets
  • The firewall management interface is temporarily unavailable

Steps to Resolve

Verify Network Connectivity

Confirm that the agent can reach the firewall's management interface:

  1. From the machine running the agent, verify basic connectivity to the firewall hostname and port
  2. Check that there are no network devices (firewalls, proxies, or load balancers) between the agent and the target firewall that might be dropping or delaying traffic
  3. If using a proxy, verify the proxy is functioning correctly and not introducing excessive latency

Check Firewall Status

Verify that the firewall is operational and its management interface is responsive:

  1. Log into the firewall's management interface directly (via web browser or CLI)
  2. Check the firewall's CPU and memory utilization - high resource usage can cause slow API responses
  3. Review the firewall's logs for any errors or warnings that might indicate performance issues

Review Network Path

If the agent and firewall are on different networks:

  1. Check for any intermediate firewalls or security devices that might be rate-limiting or blocking the connection
  2. Verify that the management port (typically 443 for HTTPS) is allowed through all network devices
  3. Consider network latency - connections over high-latency links (such as satellite or intercontinental connections) may be more prone to timeouts

Retry the Operation

Connection timeouts are often transient. The agent will automatically retry the operation, but if the error persists:

  1. Wait a few minutes and check if subsequent operations succeed
  2. If the firewall was under heavy load, the issue may resolve once the load decreases
