Description

When I install jupyter_server above 1.16.0, running jupyter lab stop to shut down server started with password pre-set will encounter an error tornado.httpclient.HTTPClientError: HTTP 403: Forbidden

# jupyter lab stop
Shutting down server on 8888...

I'm running into the same issue. Are there any alternative ways to stop Jupyter Server instances that are running in the background?
