.NET 8 C#中SslStream报“无法确定帧大小或收到损坏帧”问题求助

我有两个部署在不同服务器上的.NET 8 C#应用程序，尝试通过SslStream实现安全TCP通信，但在应用间认证环节遇到错误，希望得到解决指导。

我的消息读取代码如下：

string ReadMessage(SslStream sslStream)
{
    // 读取服务器发送的消息
    // 消息结尾以"<EOF>"标记标识
    byte[] buffer = new byte[2048];
    StringBuilder messageData = new StringBuilder();
    int bytes = -1;
    do
    {
        bytes = sslStream.Read(buffer, 0, buffer.Length);

        // 使用Decoder类将字节转换为UTF8
        // 处理跨缓冲区的字符
        Decoder decoder = Encoding.UTF8.GetDecoder();
        char[] chars = new char[decoder.GetCharCount(buffer, 0, bytes)];
        decoder.GetChars(buffer, 0, bytes, chars, 0);
        messageData.Append(chars);
        // 检查是否到达消息结尾
        if (messageData.ToString().Contains("<EOF>", StringComparison.CurrentCulture))
        {
            break;
        }
    } while (bytes != 0);

    return messageData.ToString();
}

执行bytes = sslStream.Read(buffer, 0, buffer.Length)时出现以下错误：

System.Security.Authentication.AuthenticationException: Cannot determine the frame size or a corrupted frame was received.

我已确认以下连接和证书信息：

• 协议：Tls12
• 已作为服务器认证：True
• 已加密：True
• 可读取：True
• 可写入：True
