Hello, I am running jupyterhub in a docker swarm environment. I can manage start up the jupyterhub container and authenticate to it however when I click start server it hangs for a while then I get the error that:
`Spawn failed: Server at http://<contaner if>:30030/user/jovyan/didn't respond in 300 seconds` In the docker service logs -f <servicename> I can see the following: jupyter-jovyan.1.yr4fsrhsxdef@vps147843 | Executing the command: jupyterhub-singleuser --ip=0.0.0.0 --port=8888 --NotebookApp.default_url=/lab jupyter-jovyan.1.yr4fsrhsxdef@vps147843 | [W 2020-03-26 21:12:21.487 SingleUserNotebookApp configurable:168] Config option `open_browser` not recognized by `SingleUserNotebookApp`.
