Mobile Blynk app shows Nodemcu “Wasn’t online yet”

Hello All,

I’m new to Blynk Community. I’m using this Blynk ESP8266 Standalone example to control LED connected to pin D7.
I followed Instructions as per this link

But in my Android phone the device shows “wasn’t online yet”. Pls help me out. I have checked the auth token correctly.

#define BLYNK_PRINT Serial

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "roYSZFMrGmXLDXtgDUYxE8uSLWYAdgu1";

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

void setup()
  // Debug console

  Blynk.begin(auth, ssid, pass);

void loop()

Need another Clarification. In the link above for Nodemcu board the hardware model selected as ESP8266 even though Nodemcu model is available. Can we select Nodemcu or ESP8266 is default?

You Auth token is correct, I’ve just checked and your project is on the New York server.

I assume that you’ve actually put your Wi-Fi’s correct SSID and password in the sketch before uploading it?

What does your serial monitor show?

Are you using a corporate network such as a school or business?
