If you encounter issues with a Jupyter server not starting, there are several places you can look for troubleshooting:

1. Check the plugin log file: xnat-jupyterhub-plugin.log . This log file provides insights into any erros or issues related to the XNAT JupyterHub plugin.
2. View the JupyterHub log files using the command: docker service logs SERVICE . This command allows you to access the logs generated by the JupyterHub service, and provides valuable information about the server startup process.

3. To investigate why a scheduled Jupyter server swarm task is not starting you can try the command: docker service ps SERVICE --no-trunc . This command provides detailed information about the swarm task associated with the Jupyter server service, helping you identify any errors or reasons for the failure to start.

4. To inspect a Jupyter server service and gather more information, you can use the command: docker service inspect SERVICE . This command provides a comprehensive view of the service's configuration, including network settings, environment variables, and other relevant details.
