Thanks for filing this issue and sorry you are running into this issue. Are you still running into this issue? What version of Jupyter Hub do you have installed? Can you verify you can log into Jupyter hub via the browser?

lifetooeasy commented 5 months ago

@DonJayamanne Unfortunately, I still have this issue I am running jupyterhub 1.5.0 and yes I can log in to jupyterhub.

lifetooeasy commented 4 months ago

@DonJayamanne I am running version 2.3.1 of jupyterhub now and still have same issue, do you don't think that the new versions of vscode or vscode-jupyter-hub are the cause of this issue?

lifetooeasy commented 4 months ago

could be related to microsoft/vscode-jupyter#39 ?

quantum-byte commented 4 months ago

@life Because i was looking into a similiar issue just now.

Are there any special characters in the Jupyterhub username or what does your Jupyterhub user specific instance url look like ?

DonJayamanne commented 4 months ago

@quantum-byte @lifetooeasy Please can you install this version of Jupyter Hub extension, & let me know if this works for you.

I'm having the same problem, I reinstalled using visx and still have the same problem, my username has no special characters and I'm pretty sure I can log in in my browser!

Please can you

Uninstall JupyterHub extension
Download the attached file
Extract this file
Open VS Code and select the command Install from VSIX
Select the above extracted VSIX
Enable logging (debug logging)
When prompted to reload VS Code, please do so
Try to replicate the issue once again
Capture all the logs from the JupyterHub output panel
Share the logs

ms-toolsai-jupyter-hub-insiders.vsix.zip

Screenshot for enabling logging

To get to the logs, please open the bottom output panel (use the command Outupt: Focus Output View) & then select JupyterHub

@DonJayamanne vscode can connect to remote server and list the available remote kernels. When I click on one of them the kernel is enabled BUT when I try to execute a cell I got this:

How have you started Jupyter hub? Is this locally installed?

If so please can you share the details of the versions of Jupyter hub and other packages

lifetooeasy commented 1 day ago

I am trying to connect to a remote jupyterhub not locally. It runs jupyterhub version 4.1.5 and jupyterlab 4.2.2.

DonJayamanne commented 15 hours ago

Found the reason

(Below, notes for personal use)

The docker container uses jupyterhub-singleuser to start the Jupyter Lab server customizes that program to change (approximately) one thing: authenticate requests with JupyterHub.

See here https://jupyterhub.readthedocs.io/en/latest/explanation/singleuser.html

By default, jupyter-server uses its own cookie to authenticate. If that cookie is not present, the server redirects you a login page and asks you to enter a password or token.

As a result of this, the WebSocket also needs the headers (in particular the Cookie) Without this, the websocket request is deemed un-authenticated and a 403 error is returned, thus the websocket handshake fails.

@lifetooeasy Please try installing this VSIX, should fix the issue & thanks a lot for your patience and help with this issue.

ms-toolsai-jupyter-hub-insiders.vsix (1).zip

DonJayamanne commented 13 hours ago

@lifetooeasy I think i have a better understanding of the issue now. Do you have any idea how the remote JupyterHub server has been configured.

Do you just need a user name & password to authenticate against that server when using a regular browser (outside VS Code)?
- Is this using OAuth or some other authentication mechanism?
What details are you providing when you try to connect to this from within VS Code?
