JupyterHub "Spawn Failed" Issue

[bnl]

Hi,

I installed some packages in JupyterHub, and it was working fine initially. However, after some time, I started encountering the following error:

“Spawn failed: Server at http://127.0.0.1:3333/user/user/api didn’t respond in 30 seconds.”

When I try to start my server, I see the message:

“Your server is starting up. You will be redirected automatically when it’s ready for you.”

But eventually, the spawn fails. Could you please help me troubleshoot and resolve this issue?

I have followed this tutorial: Installing on Azure — The Littlest JupyterHub documentation

Thanks in advance!

The place to start is usually looking at logs and sharing them here, if they don’t lead you to a solution directly. You’ll likely want both the hub (journalctl -u jupyterhub) and user (journalctl -u jupyter-$username) logs.
