Please help, i just copy paste from blynk example, and paste the auth token, and run the script, says it works fine, but in the app says my arduino mega havent online 
#define BLYNK_PRINT Serial1
#include <BlynkSimpleStream.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "e705eab9485d443bba30c60bae5e57a2";
void setup()
{
// Debug console
Serial1.begin(9600);
// Blynk will work through Serial
// Do not read or write this serial manually in your sketch
Serial.begin(9600);
Blynk.begin(Serial, auth);
}
void loop()
{
Blynk.run();
// You can inject your own code or combine it with other sketches.
// Check other examples on how to communicate with Blynk. Remember
// to avoid delay() function!
}
