Hi , In your widget you have mentioned that for loading the widget user needs to enter the url like http://127.0.0.1:8866 , I wonder why localhost not works instead for 127.0.0.1 ? I tried entering url like http://localhost:8866 , It give me following error : serverconnection.js:172 GET http://localhost:8866/api/kernelspecs?1541748996695 403 (Forbidden)
If I want to host this application on my secure domain , would it be possible that this work ?

This is great! @Juanlu001 A PR for this would be super useful! Initially just setting allow_remote_access to True would be enough. Later on, we could expose it as a configuration parameter.

Hi @pbugnion! I was not sure if the project was still maintained :) I am using it a lot for a freelance job so I'm pushing some updates to my fork, I will contribute them back when things have settled in a couple of weeks (I will try to take care of https://github.com/pbugnion/ipywidgets_server/issues/36 as well)

That's a valid question. I've just opened issue #48 to discuss this.
