500 errors can happen sometimes and they're indicative of transient failures on YouTube's side

@Tyrrrz This is not a transient failure, I am able to reproduce it. The issue might be specific to long duration videos, YouTube video id: IA3WxTTPXqQ is 37hrs. I was able to get manifest for videos up to 30hrs in the past without any issues.

Indeed, I can reproduce this too.
