客户端无法连接到服务器

Question

我正在尝试编写一个聊天程序，当我 go 连接时，我收到错误“无法连接，因为目标机器主动拒绝它”。 我尝试将 Server.exe 托管在两台不同的机器上，并且连接相同的客户端错误。 我检查了正在监听的端口 - 它是。 具有讽刺意味的是，当服务器在本地运行时，客户端工作得很好

客户

public Int32 port = 9818;
public TcpClient client = null;
public string serverIP = "10.0.0.72";
client = new TcpClient(serverIP, port);//Do not copy server's code for this portion

和服务器
