Why is the Jupyter Notebook in code server unresponsive?

[MrWiffer]

I can ensure that I have installed the necessary Jupyter related extensions and downloaded Python dependencies in my conda virtual environment.
When I create a .ipynb using the 【Create: New Jupyter Notebook】in 【Command Palette】, it didn't respond even after clicking all the buttons.

Are you running with HTTPS and a valid certificate? Can you post the browser console logs?

[MrWiffer]

It does seem to be related to my deployment of code server using the HTTP protocol, the console logs are shown below:

This is likely because the editor is not running in a secure context (https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts).: Error: 'crypto.subtle' is not available so webviews will not work.

[MrWiffer]

And I just learned that there are two ways to solve this problem:
a. setting up a reverse proxy;
b. adding the code server address to the browser flag management.

I want to know if there are any other ways to solve this problem?

ps: Due to certain reasons, the IP bound to the code server has to be 0.0.0.0.

Never expose a container/service on 0.0.0.0 directly.

Use a (more advanced) proxy like Træfik for your services.

HTTP only works for 127.0.0.1 / localhost
