Notebook: Notebook doesn't stop cleanly

[spencermathews]

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.

Same issue here on Ubuntu Server 18.04, except it's accessible from '0.0.0.0.'

Was using Ubuntu 16.04 and used the command:
pkill jupyter

that worked killing all the running notebooks on different ports

A server started with c.NotebookApp.password defined will disable the auxiliary token authentication. As such, when jupyter notebook stop blithely sends an empty token, the tornado server will try verifying with XSRF and fail with
403 POST /api/shutdown (127.0.0.1): '_xsrf' argument missing from POST.

One could indiscriminately set c.NotebookApp.disable_check_xsrf=true but then anybody on the internet could shutdown your jupyter instance with merely a POST request saying "api/shutdown".
