This error does not come from IPython itself, I'm trying to figure out what could cause this. 
Is there any tracebacks ?

The console log does not show anything unusual.

I added the Proxy part because it was the issue for me. I figured out because it was working when the server was on localhost and not otherwise.

This shouldn't need more configuration to work (mane clearing browser cache). 
We are still trying to figure out why it does not work on some cases.

We might need a Page that describe how to test what works and what doesn't. 

Can you try this to see if websoket works
