AVPlayer randomly fails to play video on iOS 13.6.1 and iOS 14.0.1

HLS Play back is not working on iOS 13.6.1 and 14.0.1, AVPlayer randomly fails to play the recorded content from the server.

This happens randomly and AVPlayer fails as AVPlayerItem fails even though network bandwidth is good.We checked all settings and parameters in the AVPlayer and all looks good.

With help of Wireshark tool, we even checked the video content and content looks good and same thing works fine on iOS12 version but fails on iOS 13.6.1 and 14.0.1 version.

Below is the log print observed whenever AVPlayer fails play the content.
