Troubleshoot Engine Installation

Troubleshoot failed engine installation
After installing the engine, check that the XSOAR engine is connected to the main server and that it is running.
  1. Go to
    Settings > Integrations > Engines
    and verify that the engine is connected.
  2. If the engine is not connected, run the following command on the engine server to check if the engine service is running.
    sudo systemctl status d1
  3. Access the d1 log on the engine server.
    sudo tail -f /var/log/demisto/d1.log
    • If the engine service wasn’t running, and there’s nothing relevant in the log, run
      on the engine server to understand why the installation failed.
    • If the engine service is running, review the errors to see if the engine is failing to connect or if there are other issues. (Ignore all errors related to \d2ws, since this is not the same as d1ws.) Most often, the server address is incorrect and you will see an error like this:
      error Cannot connect to [wss://<mainServerIP/HostName>/d1ws]: wss://<mainServerIP/HostName>/d1ws: dial tcp: lookup localhost: no such host. . Waiting 3 seconds. Will try until…
      In this case, navigate to
      and change the EngineURLs parameter to an address the engine can reach (such as an server external address).
    You can ignore the following error: Cannot create folder ‘/var/lib/demisto’.
  4. To check the connectivity from the engine to the main server, see Troubleshoot Engine Connectivity.
  5. If the installation issue remains, open a support case with logs from the main server and engine.
    1. On the engine server, in
      , set "LogLevel": "debug”.
    2. On the main server, navigate to
      Settings > About > Troubleshooting
      and verify that the Log Level is set to Debug.
    3. Restart the d1 service and let it run for a few minutes.
      sudo systemctl restart d1
    4. On the main server, go to
      Settings > About > Troubleshooting > Download logs
      to download a log bundle.
    5. Capture a journalctl:
      journalctl --since "1 day ago" > engineTroubleshootingJournalctl.log
    6. On the engine server, tar up the logs, conf, journalctl, and install log on the engine.
      tar -cvzf engineLogs.tar.gz /var/log/demisto /usr/local/demisto/d1.conf /tmp/demisto_install.log engineTroubleshootingJournalctl.log
