Esp32 blynk app error

I am using esp32 and I want to blink the led using wifi through blynk app. The esp32 board connected to my mobile hotspot but when I open the blynk app and set the configurations. It is showing “Blink Wasn’t online yet”
the code I used is shown below

#define BLYNK_PRINT Serial
#include <BlynkSimpleEsp32.h> 

// You should get Auth Token in the Blynk App.
char auth[] = "uhdDKK3G7vk4GzqsNLZik7cEQurNnZoq";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "yup";
char pass[] = "123456789";

int led = 33; 

void setup()
{
  // Debug console
  Serial.begin(115200);
  Blynk.begin(auth, ssid, pass);
  pinMode(led, OUTPUT);

}

void loop()
{
  Blynk.run();
}

I connected the esp32 to my mobile hotspot and i am using app from the same mobile.
I also tried connecting esp32 and mobile to a same wifi router. But it doesn’t work.
What else to do

What do you see in your serial monitor?

Pete.

You seem to have the wrong Blynk library installed.
You need to un-install it, then download and install this version…
