I constantly drop my blynk server

I made a blynk server on my ubuntu server, it happens to me that I am wanting to put some sensors, but I just put two sensors and it drops all the time I don’t know if the code is wrong or is something from my server I have the wrong code for the reconnection…

#include <SPI.h>
#include <DHT.h>
#define BLYNK_PRINT Serial  
#include <BlynkSimpleEsp8266.h>
#include <ESP8266WiFi.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27,20,4);
#include <OneWire.h>
#include <DallasTemperature.h>
#define ONE_WIRE_BUS D5 // DS18B20 on arduino pin2 corresponds to D4 on physical board "D4 pin on the ndoemcu Module"

char auth[] = "bJa4MaHmNr_YOrwoDS3lIBQUVJFazr-R";
char ssid[] = "Pablo y Maca 2.4";
char pass[] = "laputaclave";

BlynkTimer timer;

#define DHTPIN D4
   
#define DHTTYPE DHT22
#define RelayPin D6
#define RelayPin2 D7

int ReCnctFlag;  // Reconnection Flag

What does your Ubuntu server say?

As always with timers, try a lower update frequency and see if it helps (i e higher value).

Your void loop() starts with the timer.run(). What happens if you start with the blynk.run() and then your timers, which also checks your connection?!

Something like this:

void loop() {
	if(Blynk.connected()) {
		Blynk.run();
	}
	timer.run();
}

timer.setInterval(30000L, reconnectBlynk);

void reconnectBlynk() {

	if (!Blynk.connected()) {
	
		Serial.println("Lost connection");
	
		if(Blynk.connect()) {
			Serial.println("Reconnected");
		}
	
		else {
			Serial.println("Not reconnected");
		}
	}
}

Thank you very much for the help, I was right, the frequency was very low, with respect to reconnections in this way I do not drop so much, in advance thank you very much for the time spent
