We are a motorsport media outlet (the biggest in Germany). When embedding videos (any video!) from youtube, for some reason, this doesn’t work anymore.
"debug_error": "{"errorCode":"auth","errorDetail":"0","errorMessage":"Video nicht verfügbar","Ak":"Dieses Video darf nicht auf dieser Domain gezeigt werden","NQ":"0;a6s.0","hB":2}",
The same video embedded on our “sister”-page https://www.formel1.de is working correctly. So, the reason for the error CANNOT be the video itself.
I made some test pages
OK: https://www.formel1.de/ytembedtest.html
OK: https://www.ms-total.com/ytembedtest.html
NOT OK: https://www.motorsport-total.com/ytembedtest.html
(The source is always identical)
Here's a video what's happening when we're trying it:
