Esp8266 failed to restart

Hi communtiy !

I’m runing esp8266 with this sketch :

#define BLYNK_PRINT Serial


#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "xxxx";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "xxx";
char pass[] = "xxx";

void setup()
{
  // Debug console
  Serial.begin(9600);

  //Blynk.begin(auth, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 8442);
  Blynk.begin(auth, ssid, pass, IPAddress(192,168,xx,xx), 8080);
}

void loop()
{
  Blynk.run();
  // You can inject your own code or combine it with other sketches.
  // Check other examples on how to communicate with Blynk. Remember
  // to avoid delay() function!
}

All work fine exepect for restart. If i restart it don’t run sketch ( no wifi connexion, no blue LED )
I have to unpleged output 5V ( relay alimentation ) for good restarting

Some idea about this issues ?

Thanks

At least on the ESP01 the CHP_EN, GPIO 0 and 2 must be high (pullups). RST must also be high unless your resetting then it goes low and high.
