As you've mentioned it's a duplicate of #4532. Format 251 is reported to be existent but actually not on YouTube's server. There's currently no way to detect whether a file is really there or not without actual downloading. As a workaround, use:

youtube-dl -v -f 'bestvideo+171' "https://www.youtube.com/watch?v=a-mFITcJQvo" --keep-video
