I'm currently facing a 401 Unauthorized error using the ruby gem "ruby-oembed" which use oEmbed and noembed libs.
I tried it directly with oembed and noembed and I got the following result
$> https://noembed.com/embed?url=https://www.youtube.com/watch?v=3xlegeyULX8
$> {"error":"401 Unauthorized","url":"https://www.youtube.com/watch?v=3xlegeyULX8"}
and you can try it with oembed here with this youtube video https://www.youtube.com/watch?v=3xlegeyULX8
I tried to check if the video is private or has different settings but I can't find any settings different with working cases.
Any idea why it could cause it?
The video you shared 3xlegeyULX8 isn't embeddable, as YouTube Data API v3 Videos: list#status.embeddable is false for this video (cf https://www.googleapis.com/youtube/v3/videos?part=status&id=3xlegeyULX8&fields=items(status/embeddable)&key=API_KEY)
status.embeddable
boolean
This value indicates whether the video can be embedded on another website.
