iPython was working fine until a few hours ago when I had to do a hard shutdown because I was not able to interrupt my kernel. Now opening any notebook gives me the following error:

"WebSocket connection to could not be established. You will NOT be able to run code. Check your network connection or notebook server configuration."

I have the latest version of Chrome and I am only trying to access local notebooks.
The Javascript console gives me this:
