i have a problem with serial monitor “Failed to disable Echo”. Any suggestions would be appreciated.

hardware:
mega2560, esp8266

#define BLYNK_PRINT Serial    
#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>


char auth[] = "9c7ba1ed53d44a7ca8eb37afd44bcxxx";


#define EspSerial Serial1

// or Software Serial on Uno, Nano...
//#include <SoftwareSerial.h>
//SoftwareSerial EspSerial(2, 3); // RX, TX

#define ESP8266_BAUD 9600

ESP8266 wifi(&EspSerial);

void setup()
{
  Serial.begin(9600);
  delay(10);
  EspSerial.begin(ESP8266_BAUD);
  delay(10);

  Blynk.begin(auth, wifi, "Network-f81a673a63xx", "busa13xx");
}

void loop()
{
  Blynk.run();
}
