I was trying to embed a youtube video in a post and it said “Sorry, this content could not be embedded”. The console showed a 404 error trying to connect to wp-json/oembed/1.0/embed.
I tried another video and it worked. According to this stack exchange post, the first video I was trying to embed probably didn’t allow for websites to embed their content.

To get the YouTube thumbnail image, you would either use their API or a simpler method would be to use this format of the url:
http://img.youtube.com/vi/VIDEO_ID/#.jpg
Where VIDEO_ID is the last bunch of characters after “v=” in the URL: http://www.youtube.com/watch?v=0TflnHlQMt8
# is the thumbnail number. The choices are 0, 1, 2, 3. 0 is the default full size image (480×360). 2 is the default small image (120×90). 1 and 3 are other optional small images that is not the default thumbnail.
