Unable To Get HTTPS URLs (requests package)

When I try to follow the guide here: https://automatetheboringstuff.com/chapter11/ my script fails:

import requests

res = requests.get('https://automatetheboringstuff.com/files/rj.txt')
type(res)
res.raise_for_status()

requests is installed.

I am given the following error messages after a very long wait, which only appear when using HTTPS URLs; the same thing occurs on two Windows 10 64bit machines with Python 3.6.3 64bit and Python 3.6.4 64bit:

Process finished with exit code 1

Can anyone help me with this infuriating problem!!?

So it turns out the computers on my corporate network are using proxy servers, which was preventing my HTTP and HTTPS requests from connecting properly.

I followed the answer from Lelouchzqy here to determine what my HTTP and HTTPS proxy servers were.

I then followed the answer from Roland Smith here to tell requests which proxies to use.

Hopefully this will help someone in the future if they have the same issue!

You can try urllib:

Python2:

import urllib
data = urllib.urlopen('https://automatetheboringstuff.com/files/rj.txt').read()

Python3:

import urllib.requests
data = urllib.requests.urlopen('https://automatetheboringstuff.com/files/rj.txt').read()
