i used this code

define BLYNK_TEMPLATE_ID "TMPLZ5pl2Ud3"
#define BLYNK_DEVICE_NAME "TempMonitor"
#define BLYNK_AUTH_TOKEN "UFmk0JGlmqynWSBenKSCZO_jCc6KXIXd"

#define BLYNK_PRINT Serial

#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp8266.h>
#include <OneWire.h>
#include <DallasTemperature.h>
#include <SimpleTimer.h>
#define ONE_WIRE_BUS 2

OneWire oneWire(ONE_WIRE_BUS);  
DallasTemperature DS18B20(&oneWire);
float temp;

char ssid[] = "SAMSUNG Note9 WIFI";
char pass[] = "Kut19954321";
SimpleTimer timer;
char auth[] = BLYNK_AUTH_TOKEN;


void setup()
{
  // Debug console
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass);
   timer.setInterval(1000L, getSendData);
  DS18B20.begin(); 
}

void loop()
{
  Blynk.run();
  timer.run(); // Initiates BlynkTimer
}

void getSendData()
{
  DS18B20.requestTemperatures(); 
  temp = DS18B20.getTempCByIndex(0); // Celcius
  Serial.println(temp);
  Blynk.virtualWrite(V0, temp); //virtual pin V0
}

i was try, and i get the same error

Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 8080);

all libraries and boards updated to last version
is the problem with my code ?
any help ?

I don’t understand what you’re saying here. Can you clarify what you mean by this?

i am new on blynk, i saw some video on youtube told me to solve this issue I must write this step :frowning: to change port from 80 to 8080

It should be this…

Blynk.begin(auth, ssid, pass);
