Troubleshooting

  • Crusader requires that TCP and UDP ports 35481 are open for its tests. Crusader also uses ports 35482 for the remote webserver and port 35483 for discovering other Crusader servers. Check that your firewall is letting those ports through.

  • On macOS, the first time you double-click the pre-built crusader or crusader-gui icon, the OS refuses to let it run. You must use System Preferences -> Privacy & Security to approve Crusader to run.

  • The message Warning: Load termination timed out. There may be residual untracked traffic in the background. is not necessarily harmful. It may happen due to the TCP termination being lost or TCP incompatibilities between OSes. It's likely benign if you see throughput and latency drop to idle values after the tests in the graph.

  • The up and down latency measurements rely on symmetric stable latency measurements to the server. These values may be wrong if those assumption don't hold on test startup.
