AVPlayer无法在iOS 11中播放

Question

I am facing an issue with AVPlayer in iOS 11. The same code is working perfectly on iOS 10. I used DRM for playing the video.

I am getting below warning :

Please guide me. I am unable to solve this issue from last 3 days. Please let me know if you need more information about the app I used, I'll update my question.

Without code we can get the exact error descriptions. Please Post the Player creation and the steps you are using to play the file. Then only we will execute and get back to you.
