Description of your issue, suggested solution and other information

I can't download https://www.youtube.com/watch?v=3GCBekC5KX0, because it said that it doesn't exist.
However, the video does exist and it can be browsed by browser.

I couldn't find the open issue that this issue is duplicate of, or is this one a unsolvable problem?

[remitamine]

Duplicate of #18804.

I seem to get the same errors with

Requesting the webm format works. Turns out the problem is in fetching the mp4 format.

-f "webm[height=720]" instead of -f "best[height<=720]"
