The url in the error message seems valid (browser returns a response without error), and I haven't seen this error before in either Mac or Windows machines. A quick google search showed that the requests library uses urllib3 to parse url's and that in some instances when running into this error, it can be resolved by running:

python -m pip install --upgrade urllib3

Please give that a shot and let us know if it resolves the issue.

Thank you @gregmagdits, upgrading urllib3 fixed the issue.
