Notebook doesn't stop cleanly #4386
Description
jupyter notebook stop is failing, leaving the server running and forcing it to be manually killed. I observe the following output:
$ jupyter notebook stop
Shutting down server on port 8888 ...

The only modifications I've made to jupyter_notebook_config.py are:
c.NotebookApp.ip = '127.0.0.1' # 'localhost' errors with "OSError: [Errno 99] Cannot assign requested address".
c.NotebookApp.open_browser = False # I'm connecting via ssh port forwarding.
My jupyter_notebook_config.json contains a NotebookApp: password that was set up when first connecting (via JupyterLab).
I'm in the base environment of a conda install on Linux.
This configuration used to work fine, i.e. jupyter notebook stop shut down the server without error.
