error 404 in HTTP GET request with Arduino Uno and ESP8266 using AT commands when I try to send http get request I get error 404

this is my code:

#include &lt;SoftwareSerial.h&gt;

const byte rxPin = 2;
const byte txPin = 3;
SoftwareSerial ESP8266 (rxPin, txPin);

unsigned long lastTimeMillis = 0;

void setup() {
  Serial.begin(9600);   
  ESP8266.begin(115200);
  delay(2000);
}

void printResponse() {
  while (ESP8266.available()) {
    Serial.println(ESP8266.readStringUntil('\n')); 
  }
}

void loop() {

  if (millis() - lastTimeMillis &gt; 30000) {
    lastTimeMillis = millis();

    ESP8266.println("AT+CIPMUX=1");
delay(1000);
printResponse();

ESP8266.println("AT+CIPSTART=4,\"TCP\",\"alirezaabrishami.ir\",80");
delay(1000);
printResponse();

String cmd = "GET /greencare/login.php?product_id=123456 ";
ESP8266.println("AT+CIPSEND=4," + String(cmd.length() + 4));
delay(1000);

ESP8266.println(cmd);
delay(1000);
ESP8266.println(""); 
  }

  if (ESP8266.available()) {
    Serial.write(ESP8266.read());
  }

}
your HTTP request is incomplete. it should be

String cmd = "GET /greencare/login.php?product_id=123456 HTTP/1.1\r\nHost:alirezaabrishami.ir\r\n\r\n"


if the wen server host has more hostnames for the same IP address, the Host header is used on HTTP server to direct the request to the right web application
