问题描述

无论目标是 net5.0 还是 net6.0 框架，在尝试创建 sslstream 时，它在运行时反复抛出在 Ubuntu 操作系统上运行的错误Windows 操作系统，处理此错误的正确方法是什么？

错误信息

         at System.Net.Security.SslStream.ForceAuthenticationAsync[TIOAdapter](TIOAdapter adapter,Boolean receiveFirst,Byte[] reAuthenticationData,Boolean isApm)

示例代码

public static SslStream CreateSslStream(this TcpClient client,bool leaveInnerStreamOpen = false)
{
    var validationCallback = new RemoteCertificateValidationCallback(ValidateServerCertificate);
    var selectionCallback = new LocalCertificateSelectionCallback(SelectLocalCertificate);
    return new SslStream(client.GetStream(),leaveInnerStreamOpen,validationCallback,selectionCallback);
}
