Description

yt-dlp fails to extract the video at https://www.youtube.com/watch?v=dIZ-e4WwJ5w while Invidious manages it.

Is whatever bypass Invidious uses applicable to the yt-dlp code-base?

@pukkandan So reverting back the commit should solve the issue?

That commit was made because some other videos like HtVdAasjOgU was failing without it. But now it is working again 🤷. So reverting it should fix the issue
