Having issue connecting with NodeMCU Arduino.

Hi. I have big headache configuring my NodeMCU Arduino to talk to the web socket.

Here is the log from the NodeMCU :

Here is the code I use base on the ArduinoWebSocket lib.

#include <Arduino.h>

#include <ESP8266WiFi.h>
#include <ESP8266WiFiMulti.h>

#include <WebSocketsClient.h>

#include <Hash.h>

ESP8266WiFiMulti WiFiMulti;
WebSocketsClient webSocket;

#define USE_SERIAL Serial

void webSocketEvent(WStype_t type, uint8_t * payload, size_t length) {

    switch(type) {
        case WStype_DISCONNECTED:
            USE_SERIAL.printf("[WSc] Disconnected!\n");
            break;
        case WStype_CONNECTED:
            {
                USE_SERIAL.printf("[WSc] Connected to url: %s\n",  payload);

                // send message to server when Connected
                webSocket.sendTXT("Connected");
            }
            break;
        case WStype_TEXT:
            USE_SERIAL.printf("[WSc] get text: %s\n", payload);

            // send message to server
            // webSocket.sendTXT("message here");
            break;
        case WStype_BIN:
            USE_SERIAL.printf("[WSc] get binary length: %u\n", length);
            hexdump(payload, length);

            // send data to server
            // webSocket.sendBIN(payload, length);
            break;
    }

}

void setup() {
    // USE_SERIAL.begin(921600);
    USE_SERIAL.begin(115200);

    //Serial.setDebugOutput(true);
    USE_SERIAL.setDebugOutput(true);

    USE_SERIAL.println();
    USE_SERIAL.println();
    USE_SERIAL.println();

      for(uint8_t t = 4; t > 0; t--) {
          USE_SERIAL.printf("[SETUP] BOOT WAIT %d...\n", t);
          USE_SERIAL.flush();
          delay(1000);
      }

    WiFiMulti.addAP("xxx", "xxx");

    //WiFi.disconnect();
    while(WiFiMulti.run() != WL_CONNECTED) {
        delay(100);
    }
    //webSocket.beginSocketIOSSL("example.com", 1338);
    webSocket.begin("example.com", 1337, "/socket.io/?EIO=3", "wamp");
    //webSocket.beginSSL("example.com", 1338);
    webSocket.onEvent(webSocketEvent);

}

void loop() {
    webSocket.loop();
}

Here is the log on the websocket server. We can see it's connecting, but right away get disconnect.

anything I do wrong?
