Unable to connect to a Jupyter Lab server in a Docker container in a remote SSH host

[mothguib]

Environment data

• VS Code version: 1.87.2
• Jupyter Extension version (available under the Extensions sidebar): 2024.2.0
• Python Extension version (available under the Extensions sidebar): 2024.4.1
• OS and version: Windows 10 Pro 22H2, Ubuntu 23.10 Linux 6.5.0-35-generic
• Python and/or Anaconda version: 3.9
• Type of virtual environment used: Docker
• Jupyter server running: Remote

Expected behaviour

VS Code should connect to the Jupyter Server running in a Docker container on a SSH remote without returning 404 errors, allowing seamless interaction with Jupyter notebooks within the editor.

Actual behaviour

VS Code fails to connect to the Jupyter Server, returning 404 errors for /hub/api and /tree? endpoints, despite the server being accessible through a browser.

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

1. Run a Jupyter Server inside a Docker container on a remote SSH host.
2. Ensure the Jupyter Server is accessible via a browser.
3. Attempt to connect to the Jupyter Server using VS Code with the correct URI.

Logs

When entering the http://localhost:8888 or http://localhost:8888/lab URL of the Jupyter Lab, in its Docker container the Jupyter Lab returns, and VS Code asks for a password:

``` myproject | [W 2024-06-04 13:59:37.422 ServerApp] 404 GET /hub/api (8e7c766ca67041518bbe56aca79a13c2@172.27.0.1) 8.93ms referer=None myproject| [W 2024-06-04 13:59:37.425 ServerApp] 404 GET /tree? (30e563cbea704f87976dd231cc23ad1b@172.27.0.1) 0.70ms referer=None ```

Please could you enable logging as follows:

• Open settings & go into Jupyter->Logging
• Change the value to verbose
• Reload VS Code,
• Attempt to repro the issue & then copy the output from the Jupyter output panel (you can use Jupyter; Show Output to get to the logs).
