Docker container doesn't start

After the issue with the SSL connection was fixed (thank you for the quick fix for that), my deployment unfortunately still doesn't come back to life.

I get this on the logs:
```

```

which seems to be related to [this issue](https://github.com/jupyterlab/jupyterlab/issues/17012).

The Next application and API seem to run:
```

```

After that it waits forever

It is working when I run it locally, but my coolify deployment has the issue. I tried pulling, redeploying without cache etc. without any success.

Start by reproducing the Coolify deployment and compare its JupyterLab extension-manager traceback with the linked JupyterLab issue. Check the container startup logs, including the Next.js and Jupyter Server readiness messages, and trace why the deployment continues waiting for Web and API services. Done means the container starts successfully and the readiness wait completes in Coolify.
