I can login to jupyter but now have a different issue: I get the message: "A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration."

I've confirmed that any python commands I enter have no impact to the runtime. Doing Kernel > Restart results in "Not Connected" This is in Safari, on Mac 10.11.5, Python 3.5.2  Any ideas?

Can you try with another browser, to check if the problem is in the browser or further down?

Yes, I will try a couple of different configurations.

The problem is a 403 forbidden when doing a GET request on /channels?

Please go to the gist below to see the entire request/response

Google Chrome dev tools helped me determine this. Any ideas of why this may be happening even though I authenticated with the auth token at the previous login screen? Same config except the browser is Chrome(latest).

Can you check in the browser to see if the page has any cookies? Once you've used the token, it should set a cookie to authenticate you.

After that, the next thing I can think of is to put debugging print() calls into this method to see what's going on:

Chrome results in the same thing? It seems like the cookie setting has to be failing somehow, but I see the cookie in the headers. Can you reproduce this in a Private Browsing or Incognito window?

How do add logging to the runtime? I installed jupyter into a virtualenv, so what would be the path to that login.py file?

I can reproduce the issue in a Chrome Incognito window.
