Endless connection to the server

Hi. I encountered a problem that the project endlessly connects to the server without success, even though it worked a month ago with the same configuration.

I have Arduino nano and sim800l, library version 1.3.2

#define BLYNK_TEMPLATE_ID "XXX"
#define BLYNK_TEMPLATE_NAME "XXX"
#define BLYNK_AUTH_TOKEN "XXX"
#define BLYNK_PRINT Serial
#define TINY_GSM_MODEM_SIM800

#include <TinyGsmClient.h>
#include <BlynkSimpleTinyGSM.h>
#include <OneWire.h>
#include <SoftwareSerial.h>
#include <DallasTemperature.h>

char apn[] = "tele2.ru";
char user[] = "";
char pass[] = "";

#define ONE_WIRE_BUS 3

OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensor(&oneWire);
SoftwareSerial SIM800(6, 7);
TinyGsm modem(SIM800);

BlynkTimer timer;

float lastTemperature = 0.0;
bool messageSent = false;

void myTimerEvent()
{
sensor.requestTemperatures();
lastTemperature = sensor.getTempCByIndex(0);
Blynk.virtualWrite(V0, lastTemperature);
Serial.println("Current temperature: " + String(lastTemperature));


void setup()
{
Serial.begin(9600);
sensor.begin();
sensor.setResolution(12);
SIM800.begin(9600);
delay(100);

modem.restart();

Blynk.begin(BLYNK_AUTH_TOKEN, modem, apn, user, pass);

timer.setInterval(60000L, myTimerEvent);

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


}
}

This is what I get in the port monitor

Have you tried a different SIM?

Pete.

Yes, I tried 2 other SIM cards. But this one was working, the project worked from January to about March, and then this appeared

Is this the only device that uses this Blynk Auth token?

Pete.

Yes, this is the only device. For the experiment, I created an empty project and added a new token - the same thing

It’s a new device that you needed to create, not a new template.

You may need to modify your Blynk.begin() command to incorporate the server name and port. The server name should include the regional subdomain for the server wher your project lives (shown in the “About” section of the app.

Pete.

I was just creating a new device. In addition, in blynk.begin entered lon1.blynk.cloud, just my regional server. It still happens.
