Python: загрузка из защищенной папки (.htaccess)

Я установил на своем веб-сервере защищенную область. Есть два файла — один txt-файл и rar-файл. В rar-файле вы найдете pdf-файл. У меня есть исполняемая программа здесь. Сначала я получаю после успешного входа в систему содержимое текстового файла. После я беру путь (download_path = self.url.text). И сейчас я пытаюсь скачать файл. Но это не работает. Кто-нибудь может мне помочь?

Если я запускаю эту программу, я получаю следующие строки на моей консоли:
