WebPlayback SDK Initialization Error

[bluecun]

I use WebPlayback SDK to play songs in my web app. It works correctly on my local machine. 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.

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?

I discovered that in Chrome, you must access Spotify via HTTPS, that's the problem.
