I’m trying to get JupyterLab set up so that our users can launch it directly from our Open OnDemand instance. However, when you click the “connect to Jupyter” button, it results in a “The requested URL was not found on this server.” error.
If you check the logs, you can see that Jupyter launches fine:
[I 2025-01-09 13:03:29.269 ServerApp] Jupyter Server 2.14.2 is running at:
[I 2025-01-09 13:03:29.269 ServerApp] http://localhost:64987/node/n02/64987/lab
[I 2025-01-09 13:03:29.269 ServerApp] http://127.0.0.1:64987/node/n02/64987/lab
And you can access JupyterLab if you manually go to that port on a separate machine, but you can’t connect from the ood instance.
