char ssid[] = "HIRAD";
char pass[] = "%Hiradth&";
char server[] = "192.168.1.5";

void setup() {  
  pinMode(pin, OUTPUT); 
  pinMode(pin, HIGH);
  Serial.begin(115200);
  delay(10);
  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.begin(ssid, pass);
  int wifi_ctr = 0;
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("WiFi connected");

@mahdi please edit your post and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:

Was your Auth token generated through the app when it was logged-in to your local server, and did you copy/paste it directly from the email into your sketch?

You appear to be defining a variable called auth to hold your Auth token, but then not using that in your Blynk.begin command. Why?

I’m also not sure why yoiu are doing all of this stuff:

  WiFi.begin(ssid, pass);
  int wifi_ctr = 0;
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("WiFi connected");

when Blynk.begin does if for you.
