MKR1000 is not connecting with Mosquitto Broker

Hi,
I have installed Mosquitto Broker on my laptop and now I am trying to connect MKR1000 with this Broker to publish and subscribe.

MKR1000, as client, cannot connect to the Broker and mqttClient.state() returns -2.

Any hint?

Below is the code…

#include <SPI.h>
#include <WiFi101.h>
#include <PubSubClient.h>
#include “arduino_secrets.h”

///////please enter your sensitive data in the Secret tab/arduino_secrets.h
char ssid = SECRET_SSID; // your network SSID (name)
char pass = SECRET_PASS; // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0; // your network key Index number (needed only for WEP)

char topic= “news”;
const char* deviceID = “myDevice”;
int status = WL_IDLE_STATUS;

WiFiClient wifiClient;
PubSubClient mqttClient(wifiClient); // MQTT client

// MQTT Broker IP address, example:
//const char* mqtt_server = “192.168.1.144”;
const IPAddress mqttBrokerIP(127, 168, 1, 121);

void mqttCallback(char* topic, byte* message, unsigned int length){
//is executed whenever a message is arrived
Serial.print("Message arrived on topic: “);
Serial.print(topic);
Serial.print(”. Message: ");
String messageTemp;

for (int i = 0; i < length; i++) {
Serial.print((char)message*);*
_ messageTemp += (char)message*;_
_
}_
_
Serial.println();*_

}
