Прошу прощения. не владею питоном на достаточном уровне. Неправильный порядок выполнения привел к той же ошибке. к моим пулл реквестам прошу относиться с некоторым уровнем недоверия.
Верно было сначала установить context.verify_mode = ssl.CERT_REQUIRED, а затем уже вызывать context.check_hostname = True

Также хорошо было бы проверить на python 3+. У меня работает.
