beakerx: IPython: Blocking Cross Origin API request

Hi,

I am getting this error when starting IPython.

Running

1: C:\Programs\beaker/config/plugins/eval/ipythonPlugins/ipython/ipythonPlugin
2: 8804

I am running Windows 7. Is there a config file in beaker where I can set the settings for ipython to allow cross origin?

Just for those who googled this: fill into your jupyter_notebook_config.py this line:

c.NotebookApp.allow_origin = '*'

or paste your own origin.

c.NotebookApp.allow_origin = '*'

(or pass --NotebookApp.allow_origin='*' as a command-line augment)

After trying each extension, the one that failed out jupyter from working was this extension: http://lab.ejci.net/Chrome-Audio-EQ/.

I am getting similar issues:

[W 10:03:32.105 NotebookApp] Blocking Cross Origin API request.  Origin: , Host: localhost:8889

Using fedora 24, jupyter 4.2.0, and chrome 53.0.2785.143.

@scottdraves - I added this info to troubleshooting section of the wiki: https://github.com/twosigma/beaker-notebook/wiki/Blocking-Cross-Origin-API-request-error

Hope that’s ok.

@thompsonisaacb Thanks for the suggestion. This problem appeared out of nowhere, I removed Chrome EQ and the problem immediately disappeared. Could you explain what you think might have happened? Either way, thanks a million for figuring it out.

And I can confirm it works on firefox. It also works in incognito mode. It must be some extension.
