Hello Afzaal and Member1 I am having the same problem. I have multiple devices having different IPs that I want to connect them all and communicate with using my single TcpClient program. I have gone through the error code. Can you please update your recent code to communicate with multiple server with one client? Thank you.

I made connection with 2 clients and it receives message from both servers but from 1st server it receives message only once and from 2nd server  multiple times. I didnt get why it happens ? Is it closes connection with 1st server? I attached my code here please review once.

No just because you used different ports doesn't mean it is a separate client. A separate client has a separate thread to connect and communicate through. For more on TCP and sockets please read this article of mine it would clarify a few things in your mind.

Create a new client Client client = new Client(); Depending on your need you would either be using HttpClient  TcpClient or others. Check for which one do you need. Run the client on a separate thread then.

How to create multipleclients then that is initiating socket again and again.

Afzaal Ahmad Zeeshan · Answer

Indeed one client can connect to only one server at a time. To connect a client to multiple servers you would need to create multiple clients and initiate the requests to different servers. Similar process as a browser has they create a separate client for each of their thread and set their server and port to a single value throughout the execution until client requests to change the server himself. This way you would be able to create multiple clients communicating with multiple servers. A single instance of client can communicate with one and only one server at a time .
