Problem with "Home automation wasn't online yet " in blynk app version: 2.27.24

My English is not so good, because Iam from India and Iam studying in 10th.
I have a problem with my project home automation with using esp8266 and blynk app. it connected to WIFI but it is showing "Home automation wasn’t online yet "
Here’s the code

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

char auth[] = "VfhFBBSm19xN03B3BW5k1WGwbVUxN-fH"; // the auth code that you got on your gmail
char ssid[] = "Muqthadir"; // username or ssid of your WI-FI
char pass[] = "muqthadir"; // password of your Wi-Fi

void setup()
// Debug console
pinMode(D1,OUTPUT); //extend these to D8 if you are using a 8 pin relay

digitalWrite(D1,HIGH); // Make it low if you want everything to go off
digitalWrite(D2,HIGH); // in case of a power cut
Blynk.begin(auth, ssid, pass);

void loop()

@Muqthadir99 you already have an open topic

Please don’t create a multiple topics on the same subject :slightly_smiling_face:

OK but plz tell me solution.:neutral_face:

You’re using blynk legacy ( the old one ) which will be retired soon, I’d suggest that you move to the new blynk instead.
