Cannot stop Jupyter Notebook [closed]

Question

I'm running Jupyter Notebook on a remote machine where I have a password-protected account. If I run:

jupyter-notebook list

i'm told that a jupyter notebook is running at localhost:p, where p is the port. In my case, p=8890. This is fine. However, when I run:

jupyter-notebook stop 8890

I get the following errors:

Shutting down server on port 8890 ...
Traceback (most recent call last):

I know that I could stop the notebook by killing the corresponding process using kill -9, but that's not really the solution I'm looking for. Any ideas on what could cause this issue?

EDIT: As requested by @Ereli, I report the output of netstat -apn | grep 8890 (unfortunately I don't have super user rights on the machine, so the sudo part is missing)

Try pkill which combines ps aux|grep processName and kill.

pkill jupyter

should do the job. if it doesn't work, use

pkill -9 jupyter

if you want limit kill only process you own, try using the -u flag.

 pkill -u `id -u` jupyter

if you need to, kill configurable-http-proxy as that might be the file. running.

This issue seems to be open with jupyterhub team, so I assume it hasn't been fixed.
