I have a Wagtail 2.3 instance, and am embedding videos in templates from a variety of sources. A small portion of YouTube video URLs fail when attempting to embed, despite appearing to allow embedding. If I call get_embed directly, I see a HTTP 401 Unauthorized error and get_embed returns None. If I use the video embed widget on the page editor, for these URLs it fails with "Cannot find an embed for this URL."
Manually embedding any of these videos with an iframe from the "Share" frame options on these videos works fine.
An example of a video that is failing: https://youtu.be/rCvKr6nsS3w
Has anyone experienced similar with Wagtail video embedding or oembed generally? Does anyone know why these particular videos would be failing?
