404 Error on Notebook Startup

tl;dr - Any help with instructions as to how to pull not the most recent packages, but the most recent working packages to allow a working installation would be appreciated!

Hello!

Earlier this year I set up a JupyterHub server to use in my teaching following along with these directions

I have just tried to set up a second server with this software and I am getting several 404 errors when the notebook starts, proceeded by 302 redirects. They generally look like this…

[I 2020-10-25 14:21:28.339 JupyterHub log:174] 302 GET /static/components/jquery/jquery.min.js?v=20201025142123 -> /hub/static/components/jquery/jquery.min.js?v=20201025142123 (@69.144.23.87) 0.93ms
[W 2020-10-25 14:21:28.659 JupyterHub log:174] 404 GET /hub/static/components/jquery/jquery.min.js?v=20201025142123 (@69.144.23.87) 0.79ms

The hub launches fine, and users can log in with PAM authentication…

I didn’t have these problems last time - any ideas where I should look. Setting this up is at or near the limit of my ability…

Edit: I am able to - at the server’s command line use docker exec -it <container-id> /bin/bash to get into the running container JupyterHub starts… Everything works at least up to that point…

And, if I take down the firewall… it doesn’t change anything… so back up it goes… Let me know if any more information might help…

Are you using the upstream JupyterHub Docker image? There’s a known issue with some of the tags: https://github.com/jupyterhub/jupyterhub/issues/2848

In addition there’s a reported bug concerning the static files in the Docker image which may be relevant https://github.com/jupyterhub/jupyterhub/issues/3172

No. I am installing the hub into miniconda, and using a dockerspawner to spawn jupyter/datascience-notebook.

I did, however, see this issue in looking for an answer… Thanks!

I really don’t know what I am doing. Setting up servers isn’t my day job - or even a side hustle…

I have installed JupyterHub locally on my server and I am using dockerspawner to start containers of the datascience-notebook. The directions I had found worked in August - which was good, I was given days to find a way to do lab activities for my classes that were able to be done completely online…

I have been asked to “reproduce” this - and now I cannot…

Can you try turning on debug logging and see if any more information appears?

Sure!

I have continued to poke at this, I suspected that something with my apache configuration might be responsible for the 302 Redirects - so I followed these directions to configure apache to redirect to /jhub/ - as that looked the simplest…

This has made the 302 errors vanish, but I still wind up with the same 404 errors

Let me know if there is something more I can run/try to provide more information!

Could you try connecting directly to JupyterHub port 8000, bypassing Apache? For example setup an SSH tunnel to forward port 8000.

Hi Will, it’s weird that you get a 404. Is there a prefix for your url? If you just go to /hub does it redirect to your notebook?

I saw your intro post that you’re using this for Chemistry and Physics classes. You’re welcome to use our server: https://chemcompute.org/jupyterhub/submit for your classes. I’m happy to install any packages you need if they’re missing.

Thanks,
Mark

I haven’t had a chance to work on this lately. I will try this week! I appreciate the patience!

Hi markperri - I am going to try to bypass Apache (per manics suggestion) sometime this week - I am hopeful that I, perhaps, just have Apache misconfigured…

I appreciate the offer for using your server for my classes! I already have a JupyterHub server working that I am using for my classes - I was working on setting up a second - to separate family and work… I was also hoping to be able to show my IT department how easy it would be to set up - and perhaps support…

Bill

I shut down Apache entirely and I get the same result.

Any change you could share your logs again when connecting without apache?

I am facing similar problem, as I reported here: https://discourse.jupyter.org/t/jupyterhub-with-dockerspawner-error-404-when-spawning-single-user-container/6860
Have you found a solution?

Sadly, I had to take the droplet I had it installed in down - so I don’t have the logs to share. It’s unlikely I will have any further time to work on this until after next semester. I will be back - this is a very cool project!

Errors like this one are the key, I think:

All of these 404s are requests for files that should be served by the single-user server, but are being requested without the server’s base_url prefix, so they get routed to the hub and rightly 404.

The error is definitely in either the single-user server environment (possibly in the Spawner), or in the javascript of an extension. Given which URLs are missing (core files such as /custom/custom.css), my suspicion is that the base URL is not being set. Check the JUPYTERHUB_SERVICE_PREFIX environment variable in the singleuser-server environment. It should be /user/username and make sure that any templates, extensions, etc. are using variables/functions to resolve static urls, never a hardcoded /static/. Also check if --base-url is specified on the command-line.
