That's a problem on Youtube's side, other formats can be downloaded without problems, for example youtube-dl 'https://www.youtube.com/watch?v=IGgsOwfrCbY' -f 43 will download with the same resolution, but with the webm format.
I'm closing this issue because there's nothing we can do. Thanks for the report.
