Error while Playing Offline HLS Content

Hi,


Our music application play hls which is served from streamer. We are caching these music as explained here : https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/MediaPlaybackGuide/Contents/Resources/en.lproj/HTTPLiveStreaming/HTTPLiveStreaming.html


This was working, but we started to get some complaints from our users that they say that music stops while listening and can not play to end time.


These users which get this error, has these logs :


Error Domain=AVFoundationErrorDomain Code=-11800 "İşlem tamamlanamadı" UserInfo={NSLocalizedFailureReason=Unknown Error (-12645), NSLocalizedDescription=Operation not completed, NSUnderlyingError=0x282c5ea90 {Error Domain=NSOSStatusErrorDomain Code=-12645 "(null)"}}


And they are playing downloaded hls content. What is the main reason of this error and why only some of users have this error?
