Could you elaborate on "no connection"? Do you get popup error messages and are there logs in the browser console or from the Jupyter extension or JupyterHub?

OS/Web Information

• Web Browser: firefox, edge, google chrome
• Local OS: macos
• Remote OS: ubuntu-server
• Remote Architecture: arm64
• code-server --version:latest

Steps to Reproduce

1. Open Visual Studio Code on one machine.
2. Create or open a file in the editor.
3. Save the file.
4. Access the same file from a different machine using a network or cloud storage.
5. Attempt to view the file content.

Expected

I should be able to view the content of the .ipynb file from a different machine, when I accessed the vscode container using the IP address of the machine which is running the vs code container.

Actual

I am able to see the vscode when accessed over the network, but is not able to view the content of the file.

Although I can see the cells in the outline section of the vscode (bottom left)

• When accessing the vscode from the machine which is running the vscode container --> able to see the content of the file.
  

• when accessing the vscode from a different machine using ip address of the machine which is running the vscode container. ---> the file content is not visible on the editor, but we can see the content in the left side of the outline pannel

You are not using HTTPS. This is required for Jupyter notebooks.
ℹ️ Fully qualified domain name (FQDN) required, too. TLS for an IP is not sufficient.

HTTP only works for 127.0.0.1 / localhost.
