vscode-jupyter: VS Code select Existing Jupyter Server stopped working

Environment data

VS Code version: 1.79
Jupyter Extension version (available under the Extensions sidebar): v2023.5.1001582324
Python Extension version (available under the Extensions sidebar): v2023.10.1
OS (Windows | Mac | Linux distro) and version: Linux Debian Buster
Python and/or Anaconda version: Python 3.8.12
Type of virtual environment used: venv
Jupyter server running: Remote

Expected behaviour

Until this week, when I upgraded to VS Code 1.79 and latest Jupyter extension, I would typically SSH attach my VS code window to a remote machine and use a running jupyter kernel there. To do so, I’d use Jupyter: Create Interactive Window, then click on the kernel select, do Select Another Kernel, then Existing Jupyter Server, at which point i’d enter the URI and token of the server. At that point it would show me the available Python kernel to select and I’d click it.

Actual behaviour

After typing in the URI of the server, I either just get to the window that says ‘Select Kernel’ and the little blue processing bar bounces back and forth until it times out, or I see a screenshot like the one attached below which directs me to check the connecting from vs code dev link and shows that the error is ENETUNREACH, which I can’t interpret. However, as recommended in that article, I was able to confirm that I can port forward the running jupyter kernel to my local machine and view it in the browser and execute code. So, it seems the kernel is working just fine, but VS Code can’t communicate with it for one reason or another.

I encountered the same issue and rolling back the Jupyter extension to v2023.4.* did the trick for me.

Temporary work around

We’re sorry for the inconvenience caused by this issue, As a temporary solution please try the following:

Downgrade to the old extension then use the command Jupyter: Clear Jupyter Remote Server List
Upgrade to the new version of the extension
Add the new URL once again

This should allow you to use remote Jupyter servers with the latest version. Optionally you can try VS Code Insiders and the latest pre-release version of the Jupyter extesnion.

I encountered the same issue and rolling back the Jupyter extension to v2023.4.* did the trick for me.

Thanks for this @mcitoler … your suggestion of rolling back to 2023.4.x also fully resolved the issue for me!

I was having same issue as described in this thread and had tried installing all of the versions of 2023.5.x and 2023.6.x available on https://marketplace.visualstudio.com/items?itemName=ms-toolsai.jupyter > Version History, but had same issue.

I went into VS Code > Extension > Uninstall dropdown > Install Another Version, chose the 2023.4 option, downloaded the VSIX, and installed it. Now the issue is resolved!

@mcitoler @TekeDado Please could you help me figure out the problem by installing the following two VSIX

Please could you share a sample of the URL that you paste into the textbox. You can remove the server name/ip address and token.

Note: When uploading the logs, you might want to strip the server name and the token (please ensure you replace with a string such as <serverName>, <token>, this way I know you have replaced them your self.

2023.4 (from marketplace)

Please install the previous version (@mcitoler already installed this)
Reload VS Code
Try to replicate the issue (it should work, as validated by @mcitoler )
Open the command palette and select the command Jupyter: Show Output and copy the output from the output panel
(Tip: The output panel is displayed at the bottom , where the terminal is displayed, and you can also get to it using the command View: Toggle Output and then select the option Jupyter from the dropdown list displayed at the top right of the output panel)
Please remember to copy all the messages and paste it (in particular the error messages)

First VSIX (should fail)

Install this VSIX (download this file, extract it and then install using the command Extensions: Install from VSIX) ms-toolsai-jupyter-insiders.vsix (2).zip
Reload VS Code
Try to replicate the issue (this should fail with the error message)
Open the Jupyter Output panel and copy all of the output again.

Second VSIX (should work)

Repeat the same steps with this new VSIX ms-toolsai-jupyter-insiders.vsix (3).zip
Remember to reload VS Code after installing this.
This VSIX should work, however I am still interested in the logs

The logs will help me determine the difference between the versions Please do send all of the logs.

thank you for your patience and help here.
