A SOC analyst is troubleshooting an integration that intermittently fails to fetch incidents from a cloud-based security service. The XSOAR logs show 'Connection timed out' errors, but manual cURL requests from the XSOAR engine host to the service's API endpoint are successful. The XSOAR integration configuration uses a proxy server. What is the most likely cause of this intermittent failure within XSOAR?

  1. AIncorrect API endpoint URL in the integration configuration.
  2. BExpired API key used by the integration instance.
  3. CInsufficient permissions for the integration user on the cloud security service.
  4. DProxy server misconfiguration or intermittent network issues between the XSOAR engine and the proxy.
Show answer & explanation

Correct answer: D. Proxy server misconfiguration or intermittent network issues between the XSOAR engine and the proxy.

Since manual cURL requests from the engine host are successful (bypassing the proxy), but XSOAR logs show timeouts when the integration uses a proxy, the issue points to a problem with the proxy server itself or the network path between the XSOAR engine and the proxy. Intermittent timeouts suggest either transient network issues or the proxy itself intermittently failing to forward requests.

Why the other options are wrong

  • A. If the URL was incorrect, manual cURL requests would also fail, which is not the case here.
  • B. An expired API key would likely result in an authentication error, not a connection timeout.
  • C. Insufficient permissions would typically result in an authorization error, not a connection timeout.

Integration Troubleshooting: Proxy

When direct host connectivity works but XSOAR integration fails with timeouts, investigate proxy configuration or network path to the proxy.

  • Direct cURL tests bypass XSOAR's proxy settings.
  • Timeout errors often point to network connectivity or proxy issues.
  • Verify proxy address, port, and authentication within XSOAR configuration.

Memory trick: Direct success, proxy failure: check the proxy's path and settings.
