MPMoviePlayerController or AVPlayerViewController with self signed certificate

I can not get my self signed certificate to work using https with MPMoviePlayerController or AVPlayerViewController.

I've tried using AVPlayerViewController with an AVUrlAsset and a custom resource loader delegate but in ShouldWaitForResponseToAuthenticationChallenge the NSUrlAuthenticationChallenge sender is throwing a cast exception of:

Unable to cast object of type 'AVFoundation.AVAssetResourceLoader' to type 'Foundation.NSUrlConnection'

I'm not sure where to go from here. My use case is a private internal network where there is no domain or host known ahead of time, but the server and client I control.

I am using ServicePointManager.ServerCertificateValidationCallback to validate the thumbprint of my known self signed certificate for other requests which works well but I can't for the life of me get a video to play.

Anyone have any advice?

    I'm starting to think the Unable to cast object of type 'AVFoundation.AVAssetResourceLoader' to type 'Foundation.NSUrlConnection' from the NSUrlAuthenticationChallenge Sender is a bug in Xamarin.

    Did you ever find a solution to this.. your post is from 2016 and this bug is still there?? How else have developers been able to achieve range downloads (ie streaming) without using this delegate handler?

    There's a similar mechanism using MKWebView where you can assign the correct credentials when receiving an authorisation challenge from the web server. Yet this type cast exception still occurs in Xamarin when trying to access the Sender property. Anyone??
