TLS 1.2 все еще не работает с Unity 2018.2.0b3

Question

В Unity 2018.2.0b3 замечание к выпуску, упоминаемое как TLS 1.2, добавлено и работает со всеми платформами.Когда мы тестировали его, он все еще не работает и выдает некоторые ошибки.Тот же код работает в .Net application 4.5 framework .

Ошибка: SecureChannelFailure (возникла одна или несколько ошибок.) UnityEngine.Debug: Log (Object) CheckTLS: GetAuth () (вAssets / CheckTLS.cs: 31) UnityEngine.EventSystems.EventSystem: Update ()

Существуют ли какие-либо зависимости или какие-либо конкретные настройки для этого, пожалуйста, помогите решить эту проблему.
