[SOLVED] Sparkcore "your particle core is not in network"

Issues and Errors
1

Hello, I have a Spark core, I had tried to make a app with blynk, I just had been trying to turn on/off a led, but it’s doesn’t work, in particle build I put the next code:

// This #include statement was automatically added by the Particle IDE.
#include "blynk/blynk.h"

char auth[] = "xxxxxxx";

void setup()
{
  Serial.begin(9600);
  delay(5000);
  Blynk.begin(auth);
}

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

“xxxx” auth code, in the app Blynk say me, “your particle core is not in network” But my core are in my network, because I programming on cloud api.

this code I saw in http://www.sitepoint.com/how-to-make-an-effective-iot-dashboard-without-coding/

Thank You
