  标准输出: 

System.Net.Sockets.SocketException (0x80004005): 通常每个套接字地址(协议/网络地址/端口)只允许使用一次。

   在 System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress)

   在 System.Net.Sockets.Socket.Bind(EndPoint localEP)

   在 System.Net.Sockets.TcpListener.Start(Int32 backlog)

   在 dolphindb.streaming.Deamon.run() 位置 C:\Users\Administrator.WIN-LCLF8RUQNM4\source\repos\twapexcecution\bin\api-csharp-master\src\streaming\Deamon.cs:行号 83

   在 System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress)

   在 System.Net.Sockets.Socket.Bind(EndPoint localEP)

   在 System.Net.Sockets.TcpListener.Start(Int32 backlog)

配置是

 private readonly string SUB_HOST = "localhost";

        private readonly int SUB_PORT = 18802;

        //private static readonly string REMOTE_HOST = "115.239.209.228";

        //private static readonly int REMOTE_PORT = 20700;

        private readonly string REMOTE_HOST = "localhost";

        private readonly int REMOTE_PORT = 8848;

        private readonly string REMOTE_TABLE_NAME = "huobi_MarketBBO";

        private readonly int TIMEOUT = 1000;

8848是运行了服务的

修改8848为别的端口后又无法连接

请问要怎么设置才行
