Cannot access heroku apps

[hveda]

I'm using python 3.4 and here's my code:
https://github.com/retphern/hoaxbot_data_test/blob/master/lightning_scatter.py
But when i run the code, i got error like this:

Lightning initialized
Problem connecting to server at https://lightning-viz-veda.herokuapp.com
status code: 401
Traceback (most recent call last):
File "lightning_scatter.py", line 7, in
lgn = Lightning(host='https://lightning-viz-veda.herokuapp.com')
File "/home/veda/Dev/hoaxbot_data_test/venv/lib/python3.4/site-packages/lightning/main.py", line 28, in init
raise ValueError("Could not access server")
ValueError: Could not access server

But i can access the apps through web fine.

I found that this problem happen when using auth, when i delete the auth var from heroku its working fine.
