Can't connect through VSCode remote server

Bug description

Although I have followed the tutorial on this blog to configure JupyterHub to be accessed from Visual Studio Code, I still can't connect properly. The print('test') command remains stuck in execution, and the cell never finishes processing. The 'jupyter' log section shows the message:

16:09:38.542 [info] Disposing kernel .jvsc74a57bd0916dbcbb3f70747c44a77c7bcd40155683ae19c65e1c03b4aa3499c5328201f1./bin/python3./bin/python3.-m#ipykernel_launcher for notebook ~/Documents/Repositories/helm-charts/jupyter/Untitled.ipynb due to selection of another kernel or closing of the notebook

How to reproduce

1. I followed the configuration steps described in this blog.
2. In VSCode, I connected to JupyterHub and created a new notebook, selected the jupyterhub kernel.
3. In the notebook, I executed the print('test') command.
4. The cell remains in execution indefinitely, with no output. After I interrupt, these message shows:

Expected behaviour

I expected the print('test') command to execute and return the expected result in the notebook within VSCode.

Actual behaviour

The print('test') command stays in execution forever without completing or displaying any output.

Configuration

I've installed JupyterHub using the `zero-to-jupyterhub` deployment, and used the helm chart to configure it.  ``` jovyan@jupyter-vinicius-2esantos:~/.jupyter$ ls -lha total 24K drwxrwsr-x 4 jovyan users 4.0K Aug 20 16:20 . drwxrwsr-x 9 root users 4.0K Sep 17 15:54 .. -rw-rw-r-- 1 jovyan users 38 Sep 17 15:52 jupyter_notebook_config.py drwxrwsr-x 4 jovyan users 4.0K Aug 20 15:53 lab drwxrwsr-x 2 jovyan users 4.0K Aug 20 15:41 labconfig -rw-rw-r-- 1 jovyan users 32 Aug 20 15:43 migrated jovyan@jupyter-vinicius-2esantos:~/.jupyter$ cat jupyter_notebook_config.py c.ContentsManager.allow_hidden = True ```

Am I missing some thing? Can you help me to solve this issue?
