GPS/Web/WebSocket/Arduino Project

[nhatthong2k1]

Hi everybody
I am in a GPS/Web project and I am using SIM7600E module and microcontroller is Arduino Uno R3 and I have done the steps to get GPS information and internet connection by sending AT command from Arduino to SIM module and success. For the Web part, I use WebSocket protocol and I have also created a link domain and a backend. And the difficulty I have is that I cannot connect to the website. I look forward to receiving your support and thank you very much.

link Websocket I am using : GitHub - skaarj1989/mWebSockets: WebSockets for microcontrollers

#include <WebSocketClient.h>
#include <SoftwareSerial.h>
using namespace net;
 

WebSocketClient client;


  
SoftwareSerial mySerial(10, 11); // RX, TX
 

void setup() {
  mySerial.begin(115200);
  Serial.begin(115200);
  while (!Serial) {}
  
  Serial.println("Goodnight moon!");
  // Cấu hình mạng di động
  String response = sendATcommand("AT+CGDCONT=1,\"IP\",\"v-internet\",\"0.0.0.0\",0,0", 1000);
  //sendATcommand("AT+CGDCONT=1,\"IP\",\"v-internet\",\"0.0.0.0\",0,0", 1000);
   if (response.indexOf("OK") != -1) {
     Serial.println("AT+CGDCONT=1 activated");
      response = sendATcommand("AT+CGREG=1", 1000);
     //sendATcommand("AT+CGREG=1", 1000);
     if (response.indexOf("OK") != -1) {
       Serial.println("AT+CGREG=1 activated");
        response = sendATcommand("AT+CGACT=1,1", 1000);
       // sendATcommand("AT+CGACT=1,1", 1000);
        if (response.indexOf("OK") != -1) {
          Serial.println("AT+CGACT=1,1");
        }
     }

   }
   else{
     Serial.println("AT+CGDCONT=1 failed");
   }

  delay(1000);
  

  // Kết nối tới WebSocket Server
  client.open("socketmayxuciot.gorokiapp.com", 80,"/");
  client.onOpen([](WebSocket &ws) {
    Serial.println(F("Connected"));
    const auto protocol = ws.getProtocol();
    if (protocol) {
      Serial.print(F("Client protocol: "));
      Serial.println(protocol);
    }
  });
}

void loop() {
 // getGPSData(); // Lấy dữ liệu GPS

  String gpsData = "";
 
  String response = sendATcommand("AT", 1000);

    response = sendATcommand("AT+CGPS=1", 1000);
    if (response.indexOf("OK") != 1) {
      Serial.println("CGPS activated");
      delay(1000);
     // while (true) {
        response = sendATcommand("AT+CGPSINFO", 1000);
        if (response.indexOf("OK") != 1) {
          Serial.println(response);
          gpsData = response;
       //   return gpsData;         
        }
        
      //}
