Socket client is not emitting inside compute method in Flutter.

[MilindModi]

I'm trying to implement socket client connection in background using compute method of flutter. compute method with socket is working on Node.js local server and successfully emitting all the events in background. Since i hosted my Node.js socket server, client is not able to emit or listen any event. I can see logs that it's connected and i can log the Socket id as well. I'm not sure what is going wrong here.

calling of BG method compute(DummyBG,DummyArgs(message:widget.arguments.message,sender_id:widget.arguments.user_id));

DummyBG

Future forwardMessageBG(ForwardArgs args) async {
 SocketUtils _socketUtils = SocketUtils();
  
 await _socketUtils.initSocket(args.sender_id, args.user.user_id);
 await _socketUtils.connect();

 _socketUtils.socket.emit("message", [message.toJson()]);
}

SokcetUtils

class {
  var user_id;
  var recid;
  initSocket(String user_id, String reciever_id) async {
    user_id = user_id;
    recid = reciever_id;
    this._fromUser = user_id;
    await _init();
  }

 _init() async {     
   socket = IO.io(
    deployment ? _serverIP : SERVER_CHAT,
    IO.OptionBuilder()
        .enableForceNew()
        .setTransports([
          'websocket'
        ]) // for Flutter or Dart VM// disable auto-connection//
        .setQuery({
          "info": _fromUser,
        })
        .setPath(deployment ? "/chat" : "/socket.io")
        .disableAutoConnect() 
        .build());
  }
} 

nginx confingured as below.

server {
        location / {
                proxy_pass http://localhost:3000/;
                proxy_http_version 1.1;
