I can play songs. But when I deploy my app to AWS Beanstalk, the Player fails to initialize. I use fresh WebApiToken using my AWS url as redirect_url. WebApiToken is correct but initialization fails.</P><P>&nbsp;</P><P>Is there any way that I can trace the error and find out the cause of the failure? Or are there any common solutions to this problem?</P> Sat, 09 Apr 2022 19:39:05 GMT https://community.spotify.com/t5/Spotify-for-Developers/WebPlayback-SDK-Initialization-Error/m-p/5364801#M4354 user-removed 2022-04-09T19:39:05Z https://community.spotify.com/t5/Spotify-for-Developers/WebPlayback-SDK-Initialization-Error/m-p/5364803#M4355 I discovered that in Chrome, you must access Spotify via HTTPS, that's the problem.
