Enter doesn't work in "Enter the URL of the running jupyter server"

What happened?

I opened an .ipynb file, clicked Select Kernel --> Existing Jupyter Server. Then I entered https://localhost:8888 and pressed Enter. The Enter didn't register.

This is similar to microsoft/vscode#110528

I enabled trace logging, and this is the output. Note that the enter keypress doesn't show up.

Other things I tried:

• If I write https://localhost:888 and press enter, nothing happens either. A valid or invalid port is equivalent
• If I write localhost:8888 without the https, I get a pink box with a message "Invalid protocol in URL specificed, only HTTP and HTTPS are supported." Apparently in this case my Enter does register. I don't get anything in the Jupyter output, though (see below).
• Similarly if I just write localhost, I get a pink box "Invalid URL specified". In this case I do get Jupyter output.
• I restarted my computer. No change.
• I tried reinstalling VSCode. No change.
• I tried uninstalling and reinstalling the Jupyter extension. No change.
• I tried hitting the enter key more forcefully. No change. I didn't even feel better.

Running Jupyter locally or remotely?

Remote

[hroskes]

Okay, an update:

After pressing enter, I tested whether running cells in the notebook works. It doesn't. It goes back to the "Type to choose a kernel source" interface.

However, if I press Ctrl+C in the terminal where I have jupyter running, a pink box appears:

Connection failure. Verify the server is running and reachable. (request to https://localhost:8888/ failed, reason: ).

Prior to that, there is no indication that it was even trying to connect.

[DonJayamanne]

Is your jupyter server running on https://localhost:8888?

[hroskes]

It is. I can access it from the browser. (host, not hsot, I assume that was a typo)

[DonJayamanne]

Please can you open the developer tools using the command Toggle Developer Tools and go into the network tab.
Try to replicate the issue and see if there are any failed http requests or errors in the console window.
If any, please can you share the details.

[hroskes]

I'm not seeing anything there. I also redid the experiment from my second post here, where I close jupyter after pressing enter and get the error message "Connection failure...". I still see nothing on the developer tools.

[roykim98]

I'm also seeing this issue recently where I was not previously. I am able to access the jupyter server through any web browser or other client, but the extension specifically is failing to connect. All extensions and VS Code are up to date, running on Mac OS.

[DonJayamanne]

@hroskes looks like there are errors in the console tab, please can you check that

Nothing changed in Jupyter extension in this space for a few months, hence not sure

@roykim98 please can you also check the logs
