Давайте детально разберём вашу ошибку. Находится она тут - response = requests.get(url)

Ошибка типа ConnectionError сообщает нам о том, что у функции requests.get не получилось дождаться ответа от переданного ей ресурса (URL). Как так вышло?

Вы задаёте url параметр f'http://{random.choice(n)}', а random.choice(n) должен выбрать из n подходящий хост, но возвращает rian_ru?

Вряд ли у вас получится открыть сайт rian_ru правда же?

Помимо этого вам обязательно надо послушать ЭТУ песню и исправить все ошибки стилизации вашего кода, которые ужасают, простите.
