Wifi Website access Problem with arduino

Hello everyone,
i’m working on a car with 2 wheels that should work with l293d motor driver and a wifi shield .
When I put my code in arduino I’m successfully connected to my mobile hotspot and I can ping my arduino with my computer in the same network .
I really need your help guys , it’s my diploma work and Im strugging on it since 3 weeks and even the teacher didn’t understand why It didn’t worked.
The problem is when I go the link of the IP adress of my arduino I have a connection refused . Here is the code :

#include <SPI.h>
#include <WiFi.h>

#define E1 2  // Enable Pin for motor 1
#define E2 3  // Enable Pin for motor 2

#define I1 5  // Control pin 1 for motor 1
#define I2 6  // Control pin 2 for motor 1
#define I3 8  // Control pin 1 for motor 2
#define I4 9  // Control pin 2 for motor 2

char ssid[] = "Bicraveur de connexion";      // your network SSID (name) 
char pass[] = "yousslebg";   // your network password
int keyIndex = 0;                 // your network key Index number (needed only for WEP)

int status = WL_IDLE_STATUS;
void setup() {
  Serial.begin(9600);      // initialize serial communication
  //pinMode(9, OUTPUT);      // set the LED pin mode

  pinMode(E1, OUTPUT);
  pinMode(E2, OUTPUT);

  pinMode(I1, OUTPUT);
  pinMode(I2, OUTPUT);
  pinMode(I3, OUTPUT);
  pinMode(I4, OUTPUT);

  // check for the presence of the shield:
  if (WiFi.status() == WL_NO_SHIELD) {
    Serial.println("WiFi shield not present");
    while (true);       // don't continue
  }
WiFiServer server(80);

  
  // attempt to connect to Wifi network:
  while ( status != WL_CONNECTED) { 
    Serial.print("Attempting to connect to SSID: ");
    Serial.println(ssid);
    // Connect to WPA/WPA2 network. Change this line if using open or WEP network:    
    status = WiFi.begin(ssid, pass);

    // wait 10 seconds for connection:
    delay(10000);
  } 
  server.begin();
  // you're connected now, so print out the status:
  printWifiStatus();
}


void loop() {
  // listen for incoming clients
  WiFiClient client = server.available();
  if (client) {
    Serial.println("new client");
    // an http request ends with a blank line
    boolean currentLineIsBlank = true;
    while (client.connected()) {
      if (client.available()) {
        char c = client.read();
        Serial.write(c);
        if (c == '\n') {                    // if the byte is a newline character

          // if the current line is blank, you got two newline characters in a row.
          // that's the end of the client HTTP request, so send a response:
          Serial.println(currentLine.length());
          if (currentLine.length() == 0) {
            // HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
            // and a content-type so the client knows what's coming, then a blank line:
            client.println("HTTP/1.1 200 OK");
            client.println("Content-type:text/html");
            client.println();

            // the content of the HTTP response follows the header:
            //client.print("Click <a href=\"/H\">here</a> turn the LED on pin 9 on
");
            //client.print("Click <a href=\"/L\">here</a> turn the LED on pin 9 off
");
            client.print("Click <a href=\"/F\">Forward</a> to move the robot Forward
");
            //client.print("Click <a href=\"/R\">Right</a> to move the robot Right
");
            //client.print("Click <a href=\"/L\">Left</a> to move the robot Left
");
            //client.print("Click <a href=\"/B\">Backwards</a> to move the robot Backward
");
            //client.print("Click <a href=\"/S\">Stop</a> to stop the robot 
");

            // The HTTP response ends with another blank line:
            client.println();
            // break out of the while loop:
            break;
          }
          else {      // if you got a newline, then clear currentLine:
            currentLine = "";
          }
        }
        else if (c != '\r') {    // if you got anything else but a carriage return character,
          currentLine += c;      // add it to the end of the currentLine
        }

        //w Check to see if the client request was "GET /H" or "GET /L":
        if (currentLine.endsWith("GET /H")) {
          digitalWrite(9, HIGH);               // GET /H turns the LED on
        }
        if (currentLine.endsWith("GET /L")) {
          digitalWrite(9, LOW);                // GET /L turns the LED off
        }
        if (currentLine.endsWith("GET /F")) {
          digitalWrite(E1, HIGH);              // GET /F moves forward
          digitalWrite(E2, HIGH);

          digitalWrite(I1, HIGH);
          digitalWrite(I2, LOW);
          digitalWrite(I3, HIGH);
          digitalWrite(I4, LOW);

          delay(1000);                
        }
         if (currentLine.endsWith("GET /R")) {
          digitalWrite(E1, LOW);
          digitalWrite(E2, LOW);

          //delay(2000);

          digitalWrite(E1, LOW);
          digitalWrite(E2, HIGH);

          digitalWrite(I1, LOW);
          digitalWrite(I2, LOW);
          digitalWrite(I3, LOW);
          digitalWrite(I4, HIGH);

          delay(1000);
        }

         if (currentLine.endsWith("GET /L")) {
          digitalWrite(E1, LOW);
          digitalWrite(E2, LOW);

          //delay(2000);

          digitalWrite(E1, HIGH);
          digitalWrite(E2, LOW);

          digitalWrite(I1, HIGH);
          digitalWrite(I2, LOW);
          digitalWrite(I3, LOW);
          digitalWrite(I4, LOW);  

          delay(1000);
        }

        if (currentLine.endsWith("GET /B")) {
          digitalWrite(E1, LOW);
          digitalWrite(E2, LOW);

          //delay(2000);

          digitalWrite(E1, HIGH);
          digitalWrite(E2, HIGH);

          digitalWrite(I1, LOW);
          digitalWrite(I2, HIGH);
          digitalWrite(I3, LOW);
          digitalWrite(I4, HIGH);

          delay(1000);     
        }

        if (currentLine.endsWith("GET /S")) {
          
          digitalWrite(E1, LOW);
          digitalWrite(E2, LOW);

      }
    }
    // close the connection:
    client.stop();
    Serial.println("client disonnected");
  }
}
}
void printWifiStatus() {
  // print the SSID of the network you're attached to:
  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());

  // print your WiFi shield's IP address:
  IPAddress ip = WiFi.localIP();
  Serial.print("IP Address: ");
  Serial.println(ip);

  // print the received signal strength:
  long rssi = WiFi.RSSI();
  Serial.print("signal strength (RSSI):");
  Serial.print(rssi);
  Serial.println(" dBm");
  // print where to go in a browser:
  Serial.print("To see this page in action, open a browser to http://");
  Serial.println(ip);
}
  • what is you wifi shield and which pins are being used for this shield to work?
  • how is all this powered?

The problem is when I go the link of the IP adress of my arduino I have a connection refused .

where do you see the "connection refused" ?

and I can ping my arduino with my computer in the same network.

Are you sure that it is the Arduino which is responding ? I didn't know it could react to "ping".

Edit:
One suggestion is to start with a very simple web server example for your Arduino/shield, get that working, then add your application specific code.
