Hello everyone! I am a newbie here. I’ve managed to install Open OnDemand with Dex LDAP authentication, and now I’m trying to run Jupyter using this tutorial:

[https://osc.github.io/ood-documentation/latest/app-development/tutorials-interactive-apps/add-jupyter.html](https://osc.github.io/ood-documentation/latest/app-development/tutorials-interactive-apps/add-jupyter.html)

Some details:

- Resource manager: LinuxHost Adapter
- Host based authentication working between OOD node and target host
- Singularity Jupyter image tested working on target host

I’ve reached the end of the tutorial, but Jupyter doesn’t appear to be running.

This is what I do:

- Interactive Apps menu
- Jupyter Notebook
- Account: myusername, Queue: blank, Number of hours: 1 Number of nodes: 1
- Click on Launch
- I see the message “Session was successfully created” and a “card” with information: Jupyter Notebook [https://ood.laboratorio/pun/sys/dashboard/batch\_connect/sys/jupyter/session\_contexts/new](https://ood.laboratorio/pun/sys/dashboard/batch_connect/sys/jupyter/session_contexts/new)) (launched-by-ondemand-e636b9f6-8dbc-4754-be09-8ce60dc8f7e7@theia) …

But nothing more, no Jupyter web interface is available. On the compute node, I don’t see any ports open, nevertheless, I see OOD node logging in.  
No relevant information on /var/log/ondemand-nginx/user/error.log either.  
I don’t know how to continue from here, can anyone give me some hint?

Look at the output.log file in the $HOME/ondemand/data/sys/dashboard/batch\_connect/sys/bc\_jupyter directory

Thanks for your response Liu. I don’t have that file/directory:

$ ls $HOME/ondemand/data/sys/dashboard/batch\_connect/sys/jupyter/  
context.json output

$ ls $HOME/ondemand/data/sys/dashboard/batch\_connect/sys/jupyter/output/

Thanks for your help

The files are based on [GitHub - OSC/bc\_example\_jupyter: Batch Connect - Example Jupyter Notebook Server](https://github.com/OSC/bc_example_jupyter)  
Only form.yml has a change:  
cluster: “jupyter” (this is correct)

manifest.yml, submit.yml.erb, before.sh.erb, script.sh.erb, view.html.erb without changes
