youtube-dl 문제, 비공개 동영상을 다운로드할 수 없습니다

모든 비공개 동영상을 다운로드하고 싶지만 시도할 때 오류가 발생합니다. 내가 사용하는 명령줄 매개변수는 다음과 같습니다.

youtube-dl -u "Username" -p "Password" https://youtube.com/watch?v=58e_io9sIjE

출력은 다음과 같습니다.

[youtube] Downloading login page
[youtube] Logging in
[youtube] 58e_io9sIjE: Downloading webpage
[youtube] 58e_io9sIjE: Extracting video information
[youtube] 58e_io9sIjE: Downloading DASH manifest
