notebook: Connection refused

Every time I launch the Jupyter notebook using

jupyter-notebook

I get a

Connection refused: localhost:8888

I have to replace localhost with 127.0.0.1 for it to work.

This occurs with all browsers I use: Opera, Firefox, Chromium OS: Ubuntu Gnome 16.04

@takluyver I just found out that it happens because I had Turbo mode on.

Aha. I think ‘Turbo’ mode in Opera uses a proxy server to prefetch pages. I’m surprised it doesn’t know to skip that for localhost, but I guess it doesn’t.

I have the same issue both with and without opera turbo, with or without VPN. If anyone finds a workaround, I’d be happy to hear about it

@takluyver @gnestor Running it runs: Serving HTTP on 0.0.0.0 port 8888 ... until I close it.

I should update you that it is not working just in Opera. In Firefox and Chromium it works.

When Opera is used the url being used is http://openurl%28http//localhost:8888/tree,new-page). And when using localhost:8888/tree) I get the Connection error.

That sounds like something is misconfigured in Opera.
