Sending Data to Online Server using ESP

Hi, I've been working to send ESP 8266-01 data to my Online Server.

Whenever I try to send to the local one such as my PC IP Address it works, but when switching back to the Online Server no data has been sent and save to database.

Here's my sketch for your reference

#include <TinyGPS++.h>
#include <SoftwareSerial.h>

static const int RXPin = 11, TXPin = 10;
static const uint32_t GPSBaud = 115200;

// The TinyGPS++ object
TinyGPSPlus gps;

// The serial connection to the GPS device
SoftwareSerial ss(RXPin, TXPin);


void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  ss.begin(9600);
  Serial.println("AT+CWMODE=1");
  delay(1000);
  Serial.println("AT+CWJAP=\"Chaenelle\",\"iceangel1011\"");
  delay(1000);
  
}

void loop() {
  // put your main code here, to run repeatedly:

  while (ss.available() > 0){
      gps.encode(ss.read());
      if (gps.location.isUpdated()){
            int MHMQ = MH();
            int MQT = MQ();
          Serial.println("AT+CIPSTART=\"TCP\",\"www.airqualitymonitoringsystem.xyz\",80");
          delay(1000);
          Serial.println("AT+CIPSEND=88");
          delay(1000);
          Serial.print("GET /application/api.php?mqh=");
          Serial.print(MHMQ);
          Serial.print("&mq=");
          Serial.print(MQT);
          Serial.print("&lat=");
          Serial.print(gps.location.lat(), 6);
          Serial.print("&longi=");
          Serial.println(gps.location.lng(), 6);
          delay(3000);
          Serial.println("AT+CIPCLOSE");
        
    }
  }



  
//  delay(5000); // delay in between reads for stability
}

int MH(){

  int MHPin = analogRead(A0);

  return MHPin;
}

int MQ(){
  int MQ = analogRead(A1);

  return MQ;
}

Thank you for your help

If you are sending through a GET request - you should get a response from the server.
What response are you getting?

What does the request look like when you are sending it through to the local server?
Maybe something simple is missing from the request?

Is there a reason you are using GET instead of POST ?
