Observing values ​​on AVPlayerItem in iOS9

I have an application that uses AVPlayer

to play AVPlayerItem

(video) from a remote url. In iOS 6-8 I watched the value AVPlayerItem's

for loadedTimeRanges

to notify me when the playerItem

player is ready to play. This also works when I observe the value for an element duration

.

After upgrading to iOS 9 beta, none of the values ​​in AVPlayerItem

that I observe ever turn into a method observeValueForKeyPath

. As if I don't watch them at all. I am still being notified by values ​​on AVPlayer

, but not on AVPlayerItem

. Could this be a mistake or change something in the environment here? I can't find anything about this.

To clarify, in iOS 6-8, videos start playing as soon as time ranges are loaded. In iOS9, I am never notified when any time intervals are loaded.

Update

After observing the value status

for, AVPlayerItem

I have now confirmed that the item's status has changed to Failed

. After completing the item NSError

after failing, I get this:

Error Domain=AVFoundationErrorDomain Code=-11800 
    "The operation could not be completed" 
    UserInfo=0x146023c90 {NSUnderlyingError=0x144f547d0 
    "The operation couldn’t be completed. (OSStatus error -1022.)",
    NSLocalizedFailureReason=An unknown error occurred (-1022), 
    NSLocalizedDescription=The operation could not be completed}
