Screenshots

I have a JS notebook running in Codespaces. When I try fetching any URL through localhost from the notebook, it does not connect.
I can confirm the server is running, as running curl http://127.0.0.1:11434 in a terminal works fine.

Is there anything I'm missing, or is this maybe related only to devcontainer/Codespaces environments?

[jonsequitur]

The Polyglot Notebooks JavaScript kernel runs in the browser, not on the server.

The Polyglot Notebooks JavaScript kernel runs in the browser, not on the server.

I'm not sure what you mean by that?
Even when running it on my local machine, this does not work. If I open http://127.0.0.1:11434 in my browser, this works. So even if the kernel is running in a different context that the VS Code backend, when running this locally I don't see why this should not work?

To make thing complete, even a simple call to https://www.google.com fails. I've also seen other having difficulties making HTTP call here: https://learn.microsoft.com/en-us/answers/questions/1289426/how-to-correctly-execute-requests-to-the-server-in

Being unable to make HTTP calls from a JS kernel makes it mostly useless, is there any kind of workaround for this?
