AVPlayer CoreMediaErrorDomain -12642 -12880

Hi everyone, I am having a problem on AVPlayer when I try to play some videos.

The video starts for a few seconds, but immediately after I see a black screen and in the console there is the following error:

https://...manifest.m3u8 -12642 "CoreMediaErrorDomain" "Impossibile completare l'operazione. (Errore CoreMediaErrorDomain -12642 - No matching mediaFile found from playlist)"

-12880 "CoreMediaErrorDomain" "Can not proceed after removing variants" -

The strange thing is that if I try to play the same video on multiple devices, the result is that on someone it works and on someone it does not. For example on iPhone 5SE works and on iPad Pro 11'' II gen. and iPhone11

I've tried searching around to figure out what may be causing the problem, but there doesn't seem to be a clear solution.

Anyone who has had a similar problem? Do you have any ideas about the reason for this problem?

Do you get these on VOD or Live streams?

Suspecting this is due to missing discontinuity synchronization between variants.

Do you have discontinuities (#EXT-X-DISCONTINUITY) in your media playlists? If yes - do you maintain discontinuity sequence (#EXT-X-DISCONTINUITY-SEQUENCE)?

HI,do you fix this issue? "No matching mediaFile found from playlist"
