Mkr1000 - Blynk Communication error

Need Help With My Project
1

Hello, I am new to Blynk. I am trying to use the Arduino OTA and Blynk library on a mkr1000.
The problem is that I lose communication with the Blynk application and the mkr1000.

#define BLYNK_PRINT Serial
#include <SPI.h>
#include <WiFi101.h>
#include <ArduinoOTA.h>
#include <BlynkSimpleMKR1000.h>
#include "arduino_secrets.h" 
#define dos 2
///////please enter your sensitive data in the Secret tab/arduino_secrets.h
/////// Wifi Settings ///////
char auth[] = "eWztXuaiQm9xBFK9uvxpKiC_eJCYLisO";
char ssid[] = "precise24G";
char pass[] = "costaR1ca";   

int pinvalue;

int status = WL_IDLE_STATUS;

BLYNK_WRITE(V1)
{
  pinvalue = param.asInt();
  if(pinvalue==true){
    digitalWrite(dos,1);
  }
  else {
    digitalWrite(dos,0);
  }
}

void setup() {
  //Initialize serial:
  Serial.begin(9600);
  Blynk.begin(auth,ssid,pass);
  pinMode(dos,OUTPUT);
  // check for the presence of the shield:
  if (WiFi.status() == WL_NO_SHIELD) {
    Serial.println("WiFi shield not present");
    // don't continue:
    while (true);
  }

  // attempt to connect to Wifi network:
  while ( status != WL_CONNECTED) {
    Serial.print("Attempting to connect to SSID: ");
    Serial.println(ssid);
    // Connect to WPA/WPA2 network. Change this line if using open or WEP network:
    status = WiFi.begin(ssid, pass);
  }

  // start the WiFi OTA library with internal (flash) based storage
  ArduinoOTA.begin(WiFi.localIP(), "Arduino", "password", InternalStorage);

  // you're connected now, so print out the status:
  printWifiStatus();
}

void loop() {
  Blynk.run();
  // check for WiFi OTA updates
  ArduinoOTA.poll();

  // add your normal loop code below ...
}

void printWifiStatus() {
  // print the SSID of the network you're attached to:
  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());

  // print your WiFi shield's IP address:
  IPAddress ip = WiFi.localIP();
  Serial.print("IP Address: ");
  Serial.println(ip);

  // print the received signal strength:
  long rssi = WiFi.RSSI();
  Serial.print("signal strength (RSSI):");
  Serial.print(rssi);
  Serial.println(" dBm");
