java.net.ConnectException: Connection refused

问：

　　I'm trying to implement a TCP connection, everything works fine from the server's side but when I run the client program (from client computer) I get the following error:

java.net.ConnectException: Connection refused

答：

　　Please check:

  • Host name and port you're trying to connect to
  • The server side has managed to start listening correctly
  • There's no firewall blocking the connection
