自从发布iOS 13以来，我在我的iOS应用程序中遇到了一个奇怪的问题，由于与后端的TLS连接错误。如果我尝试通过模拟器（iOS 13）连接到后端，它可以正常工作，但如果我将应用程序安装到物理设备上（iOS 13.1），由于以下原因就无法连接：

Si è verificato un errore SSL ed è impossibile effettuare una connessione sicura con il server.
显然后端是相同的，由AWS证书管理器创建的aws证书覆盖了它。我认为问题不在于证书，因为我认为它符合新的苹果证书政策，但我无法理解问题出在哪里。
你能帮帮我吗？
谢谢
