GSM module stopped working

[ritikpindoria]

Hi,
I am trying to upload data collected by the Arduino to the internet with the aid of a sim7600 G-H. i have been able to do so using AT+MQTT style commands and now want to do it without MQTT. Nothing seems to work and after running the code below, the module completely refused to connect to the network. Could anyone please help with this.
Thank you.

// Define the APN (Access Point Name) for your cellular network provider
const char* apn = "telstra.m2m";

// Define the server and resource
const char* server = "httpbin.org";
const int serverPort = 80;
const char* resource = "/get"; // This endpoint returns information about the request

void setup() {
  Serial.begin(115200);
  Serial1.begin(115200); // Use Hardware Serial 1 for LTE module communication

  // Initialize the LTE module
  lteInit();

  Serial.println("Ready to make HTTP requests.");
}

void loop() {
  // Connect to the internet
  if (lteConnect()) {
    // Make an HTTP GET request to httpbin.org
    sendHttpRequest(server, serverPort, resource);

    // Disconnect from the internet
    lteDisconnect();
  }

  delay(5000); // Wait for 5 seconds before making the next request
}

void lteInit() {
  Serial1.println("AT"); // Send AT command to wake up the module
  delay(1000);
  Serial1.println("AT+CGATT=1"); // Attach to the network
  delay(2000);
  Serial1.println("AT+CNMP=13"); // Set network mode to LTE
  delay(1000);
  Serial1.print("AT+CGDCONT=1,\"IP\",\"");
  Serial1.print(apn);
  Serial1.println("\""); // Set the APN
  delay(1000);
}

bool lteConnect() {
  Serial1.println("AT+CGATT?");
  delay(500);
  while (!Serial1.find("+CGATT: 1")) {
    Serial.println("Connecting to LTE network...");
    delay(2000);
    Serial1.println("AT+CGATT=1");
    delay(2000);
  }
  Serial.println("Connected to LTE network.");
  return true;
}

void lteDisconnect() {
  Serial1.println("AT+CGATT=0"); // Detach from the network
  delay(2000);
  Serial1.println("AT+CFUN=0"); // Turn off the module
  delay(2000);
}

void sendHttpRequest(const char* server, int port, const char* resource) {
  Serial1.print("AT+HTTPPARA=\"CID\",1\r\n");
  delay(1000);

  Serial1.print("AT+HTTPPARA=\"URL\",\"http://");
  Serial1.print(server);
  Serial1.print(":");
  Serial1.print(port);
  Serial1.print(resource);
  Serial1.println("\"\r\n");
  delay(1000);

  Serial1.println("AT+HTTPACTION=0\r\n");
  delay(1000);
}
