My Question or Issue

I'm embedding my Spotify hosted podcast on a partner website. Everything was fine until last week. Since, embedded episodes cannot be played anymore. I get this errors in my browser console :

Access to audio at 'https://anchor.fm/.../.mp3' from origin 'https://my-partner-website.tld' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
GET https://anchor.fm/.../.mp3 net::ERR_FAILED 302 (Found)

 
Is there anyway to fix this ? 

EDIT : I'm trying to embed on this website https://www.radiofrance.fr/savoirs-plus/podcasts/serie-les-volontaires
