ESP32, Wifimanager, integration with Blynk

board : ESP32 IOT DEV BOARD 30PIN
blynk server

I made numerous attempts, among these I attach the semi-functioning one. the problem is that the connection to the blynk server continues to reboot.

Can anyone help me? COSTAS!! please help me!

    wifiManager.setConfigPortalTimeout(180);


      
    delay(1000);
  }
ticker.detach();
digitalWrite(LED_PIN, HIGH);


timer.setInterval(30000L, reconnectBlynk);  // check every 30s if still connected to server 
  Blynk.config(auth);
  int mytimeout = millis() / 1000;

    if((millis() / 1000) > mytimeout + 8){ // try local server if not connected within 9 seconds
       break;
    }
  }
}

void loop()
{

  int count = 0;
    
    if (Blynk.connected()) {
    Blynk.run();    
  }
  timer.run();
  Blynk.run();
  


// Reset the network
  while(digitalRead(TRIGGER_PIN) == LOW) {
    delay(100);
    count++;
    if(count > 30) {
      //ESP.eraseConfig();
      WiFi.disconnect();
      digitalWrite(LED_PIN, LOW);
      delay(1000);
      count = 0;
      digitalWrite(LED_PIN, HIGH);
      delay(100);
      ESP.restart();
      delay(1000);
    }
  }EEPROM.commit();
}

That void loop looks very messy.
You have two Blynk.runs in there, plus this blocking while loop.

What happens if you trim this down to just Blynk.run and timer.run in the void loop?

Pete.

Is the same result. thanks a lot for help.
