ESP8266 stopped work after deepsleep

Hi everyone, I don’t know why after deepsleep ESP show a message and stop.

Could you help me please?

As you can see, this is a simple code:

void setup()
{
    Serial.begin(115200);
    Serial.println("");
    Serial.println("Setup...");

    Serial.println("Sleeping...");
    delay(100);
    ESP.deepSleep(5 * 1000000);
    delay(100);
}

And this is the result:

The correct place for your question is http://www.esp8266.com and https://stackoverflow.com/

The ESP GitHub is having a long overdue purge of anything that is not related to code i.e. “how do I …” and "when will … " type questions etc.

Espressif.com also has their own forum.

Precisely which ESP do you have?
You state stopped working does that mean deepSleep was working and it’s now stopped and if so how long have you been using it?
If you have just started using deepSleep do you have the correct pin connections for the wake up procedure?
