Running Python script with oauth2 via matlab

I'm trying to run a Python script that updates a Google spreadsheet with values calculated with Matlab. I'm using the gspread API, which uses oauth2. Running straight Python, I'm able to download and modify spreadsheets without a problem. When I try to run the script in Matlab, I get the following error when I try to authorize the credentials:

Python Error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600)

Any ideas about what I could do to solve this? I suppose the workaround would be to just save the data from Matlab and import the .mat file into Python.

I'm curious, which version of Python are you using? Certificate verification was turned on by default in 2.7.9 and 3.4.3 [1, 2, 3]. Also, are you using the same Python version when you run the script in MATLAB and when running straight Python?
