My esp32 can connect to wifi, but have no internet access

Using Arduino Project Guidance

Hi guys, I really need help.

i have an esp32 and am trying to connect it to wifi. My ESP32 can connect to WiFi, but when I try to test the connection to Telegram it fails. I think it's because the esp32 doesn't have internet access.

when I use hotspot tethering from the smartphone then the esp32 has internet access

there is the code :

#include <Arduino.h>
#include <WiFi.h>
#include <CTBot.h>

 String ssid = "Untan2023";
 String pass = "Informatika";
 String token = "************************";


void setup() {

  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  delay(500);
  WiFi.begin(ssid, pass);

  int reset = 0;
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    reset ++;
    Serial.print("Menyambungkan ke WiFi : ");
    Serial.println(ssid);
    if (reset == 5) {
      ESP.restart();
    }
  }     
  if (WiFi.status() == WL_CONNECTED){
    Serial.println("Wifi is Connected");
  }  else {
    Serial.println("Wifi is Not Connected");
  }
  
  delay(500);
  myBot.setTelegramToken(token);      
//connect telegram bot
  delay(500);
  if(myBot.testConnection()) {
    Serial.println("\nKoneksi ke Telegram Berhasil !");
  } else {
    Serial.println("\nKoneksi ke Telegram gagal !");
  }

}

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

}

Is this really a bug in esp32?
or
are there any wifi settings that need to be changed?
how to solve this problem?
i really thanks for your help.
