This helped resolve my issue: Thanks to the blog by Yifan Peng : http://blog.pengyifan.com/how-to-fix-python-ssl-certificate_verify_failed/

I added the below code:

import os, ssl
if (not os.environ.get('PYTHONHTTPSVERIFY', '') and
    getattr(ssl, '_create_unverified_context', None)): 
    ssl._create_default_https_context = ssl._create_unverified_context

For the record, this error is almost certainly due to the following combination of events:

• The certificate database of the operating system on which the script is run is outdated.

• You are running Python 2 >= 2.7.9 or Python 3 >= 3.4

In these versions of Python, SSL certificate verification is turned on by default (in previous versions, it was turned off by default). The solution is to update your OS’ certificate database, which differs greatly per OS.
