Photon not online in Blynk app via local blynk server

Hello everybody,

I have trouble running a photon (with following code) connected to a Blynk local server. The problem is that my Blynk app is reporting that the photon is not online. I get no errors just that the photon is not online. I am certain about the authorisation code, the ip for the blynk local server and also about the blynk local server itself. The firmware of the photon is 0.7.0. The LED-indication on the photon shows no problem.

Anybody an idea what is wrong?

Thanks in advance,

#include <blynk.h>
#define BLYNK_PRINT Serial
char auth[] = "0338485e588e47a0ae39868db60124c7";

Servo motor;

void setup()
    delay(5000); // Allow board to settle
    Blynk.begin(auth, IPAddress(192,168,0,101), 8080);

void loop()
