Timeout error when trying to connect to the gmail api

[jose-ramirez]

Expected Behavior

quickstart.py should work as intended, showing the user's labels as queried from the user's gmail account.

Actual Behavior

timeout error before creating the token.pickle file:

I tried with both of my system's python versions as well (2.7.17, 3.7.6), same error. I have reasons to believe it's something about my system, since it happens for three different python versions, I tested Java's quickstart code with the same credentials and it worked as expected, and python's version was working until last week, but don't know where to look to fix it, so, any help will be appreciated.

Steps to Reproduce the Problem

1. Create a virtual env with python 3.6.4.
2. Run python quickstart.py

Specifications

• Python version (python --version) 2.7.17, 3.6.4, 3.7.6
