Xamarin forms Plugin.MediaManager video not played from url due to ssl.

the error is ssl certificate ,so i add in main activity this code

System.Net.ServicePointManager.ServerCertificateValidationCallback +=
delegate (object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate,
System.Security.Cryptography.X509Certificates.X509Chain chain,
System.Net.Security.SslPolicyErrors sslPolicyErrors)
{
if (sslPolicyErrors == System.Net.Security.SslPolicyErrors.None)
return true;

// Do not allow this client to communicate with unauthenticated servers.
return false;

};

when i used any other link for video then video play but my server video still not play on android but now on IOS video play.
