with jupyter_notebook_config.py can't start the jupyter

[mattshma]

When I copy the jupyter_notebook_config.py to $HOME/.jupyter/, I can't start the jupyter notebook:

jovyan@11821ce44fe1:~/.jupyter$ jupyter notebook

If I delete $HOME/.jupyter/jupyter_notebook_config.py, it could works!

I find jupyter/notebook#3754 have some problem, but I had updated my notebook..

Any helps?

[mattshma]

I find c.NotebookApp.ip = '*' cause this problem. when I change c.NotebookApp.ip from * to 0.0.0.0, the jupyter could start.

[avinson]

@mattshma you should re-open this because it's still broken without the workaround

[parente]

Fixed in #721

not working

[Franselbaer]

Please double check if you have anywhere a startup script with --ip="*" and change it to --ip="0.0.0.0". It really helps.

[Franselbaer]

What a good idea to change that in minor release without deprecated warning... 🙄

[dimitri320]

This still doesn't solve the error when you're running Jupyter on AWS. Any ideas what can fix it?

Commenting line "-----.ip = '*'" in jupyter config file worked for me.

I have the same issue. Any new solutions?

[romainx]

@Mjvolk3 could you please give a reproducible example, as things have changed since this issue was opened.
Many thanks
