wcf - 服务器已拒绝客户端凭据

Question

我有一个带有 net.tcp 绑定(bind)的 WCF 服务，作为 Windows 服务托管在服务器上。我无法访问此服务。但是，当我将它托管在本地网络上时，我能够这样做。
收到错误

Message:** The server has rejected the client credentials.

Inner Exception:

System.Security.Authentication.InvalidCredentialException:
The server has rejected the client credentials.
---> System.ComponentModel.Win32Exception:
The logon attempt failed --- End of inner exception stack trace

尝试搜索解决方案，但没有找到符合我要求的解决方案，因此在此处发布。
可能是什么问题呢？
如果我在客户端将我的安全模式设置为无

<security mode="None"></security>

我得到另一个错误:

Error: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00:59.5149722'.

我刚刚遇到了同样的问题，试图在 DMZ 中获取服务器与我网络内的服务交谈。为我修复它的解决方案是将以下内容添加到 app.config:

注意安全节点。

<bindings>
  <netTcpBinding>
    <binding name="customTcpBinding" maxReceivedMessageSize="20480000" transferMode="Streamed" >
      <security mode="None"></security>
    </binding>
  </netTcpBinding>
</bindings>
