The client keeps on reconnecting

[hungthuanmk]

I am trying to make communication between Server (Java) and React Native App on phone It works well with Server written in Node.js but the client keep retrying to connect to server written in Java with netty-socketio ver 1.7.16 Here is my code:

public static void main(String[] args) {
        Configuration config = new Configuration();
        config.setPort(3000);
        final SocketIOServer server = new SocketIOServer(config);

        server.addEventListener("msg", String.class, new DataListener<String>() {
            public void onData(SocketIOClient client, String data, AckRequest ackRequest) {
                System.out.println("Received: " + data);
            }
        });

        server.addConnectListener(new ConnectListener() {
            public void onConnect(SocketIOClient socketIOClient) {
                System.out.println(socketIOClient.getSessionId() + " had just connected!");
                socketIOClient.joinRoom("room1");
            }
        });

        server.start();

        while (true) {
            server.getBroadcastOperations().sendEvent("img","This is msg from server");
        }
        server.stop();
    }

And here is console output when react native app run

Check your client transport. If you set polling, websocket.

First, connect HTTP long-polling. After client will be try connect websocket.

see this page. https://socket.io/docs/client-api/#With-websocket-transport-only
