无法使用来自 LAN 中 Unix 系统的 Websocket 从客户端连接 Node.js/Socket.io 服务器

Question

I have written a client application in C++ using websockets in Unix Environment trying to connect a Node.js/Socket.IO server running in a LAN connectivity. I found the server application is not responding at all. I tried a couple of other options from client side eventually getting no response from the server. Basically, i am trying to send a JSON object to the system running SocketIO server, but the client is not getting connected even if the server listens on to a Port. Help, is really appreciated. Thank you.

Make sure following has been checked-

1. Server running and port is open (firewall) - Client is unable to connect the server
2. Url is correct - Client is unable to connect or url not exist
3. Listener code or receiving task is running - Client connected but when server send data to client, client didnot receive data
4. JSON format is correct and json data does not contain invalid character - client send data server but server did not received

Follow - remove date if exists into msg for test purpose, use " to prepare JSON data, donot put / end of the url if not required. example- 1. Write url as ws://abc.com:8080/wsserver 2. JSON data as {"name":"myname","yourname":"indo","msg":"birthday"}
