`ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)` When opening sheet

See original GitHub issue

After successfully authenticating I’m getting an SSL error whenever I try to open a sheet.

scope = ['https://spreadsheets.google.com/feeds']
credentials = SignedJwtAssertionCredentials(GOOGLE_AUTH['client_email'], GOOGLE_AUTH['private_key'], scope)
gc = gspread.authorize(credentials)

sh = gc.open('Genesis-QuestionBank')

So, I don’t know what happened, but for some reasons python package Requests 2.16.0 started requiring Certifi, which causes this SSL error. I had to specify version 2.15.1 to be able to uninstall certifi and restore service to my automation. pip install requests==2.15.1; pip uninstall -y certifi

I thought I posted a comment about what this was for me - it turned out the Python package “certifi” which is part of a other Python package “Tornado” was causing this error. I used:

pip uninstall -y certifi

And the error went away, and Tornado appeared to still work.
