I created new jupyter notebook in VS Code and then I execute cell but there were forbidden errors.

How can I solve this problem??

Please could you upload some sample code so I could relate this at my end.

Same here on Windows 10 x64 (latest updates). As far as I can tell, the extension doesn't launch a notebook / can't connect to Jupyter kernel. It seems as if there are multiple notebooks still running. In some cases, using taskkill to end all jupyter-notebook and python processes or restarting the OS would help.

This might help someone, what I did was copy the token url from the jupyter notebook output tab (down right) and insert it in the "enter url of local/remote notebook" promt.

I've been having this problem, thought it was an extension bug so I stepped through the code, turns out that "jupyter notebook list" was returning stale values, and that waitForNotebookToStart() in src\jupyterServices\notebook\utils.ts pulls out the token for the first session it finds

solution: delete the stale files located at %APPDATA%\jupyter\runtime\nbserver-*.json

There's a separate bug where closing vscode leaves an unattached notebook process running (don't know if it's a bug or feature), but if you've been killing those memory hungry processes with taskmanager that could be causing the problem.

@DonJayamanne, in looking at this, I ended up refactoring some of the code away from promise then(), catch() (was going cross-eyed following and stepping that logic) to async/await (much cleaner looking IMO). It compiled and ran fine with target: "es2017" under latest stable vscode. Any plans to refactor parts of the plugin? (would make it easier to contribute)
