Youtube Embedding not working

Hi, youtube embeds are not working on ghost 3.0.2 (istance at with Safari and Chrome on macOS. It says “There was an error when parsing the URL”, the url is
In console it says [Error] Failed to load resource: the server responded with a status of 422 ( (oembed, line 0)

Any ideas?
Thanks in advance.

It might be that the video you’re trying to embed does not allow embedding or is otherwise disabled somehow. It looks like it is copyrighted content (The Simpsons) posted by someone other than the author, so that could be related.

I just embedded another Youtube video just fine.
