Interactive python window not launching on code cell execution

I used the [medium blog](https://medium.com/datamindedbe/customizing-sagemaker-notebook-instances-29f919421e24) to setup code-server in a notebook instance. Only change I made was using the latest release https://github.com/aws-samples/amazon-sagemaker-codeserver/releases/download/v0.2.0/amazon-sagemaker-codeserver-0.2.0.tar.gz.

I then installed the Jupyter extension through the gui and tried to execute a code cell. However the interactive python session just infinitely hangs. The same happens when i launch a notebook.


Any suggestion on how to debug this? My guess is pre installed jupyter config is different and vscode can't find an active server instance.
