Alexa not discovering ESP8266

Hi,

I am having trouble connecting Alexa to my ESP8266. The ESP8266 is connected to my wifi and I can ping it with no problems. when I try to discover the ESP on Alexa it cant discover it. Is anyone else having this problem? It’s an Alexa 3rd Gen. When I ask Alexa to search for new devices the blue LED on the ESP flashes for a split second.

Thanks,
Mike.

  Serial.println(ssid);
  WiFi.begin(ssid, password);

  Serial.println(ip);

  wemoManager.begin();
  
  // Format: Alexa invocation name, local port no, ON callback, OFF callback.
  ChristmasLights = new WemoSwitch("Christmas Lights", 80, ChristmasLightsOn, ChristmasLightsOff);
  wemoManager.addDevice(*ChristmasLights);

  delay(10);

  //Setup 433mhz Transmitter.
  mySwitch.enableTransmit(16); // Transmitter DATA Pin is connected to Pin D0.
  mySwitch.setProtocol(1); // Set protocol.
  mySwitch.setPulseLength(165); // Set pulse length.
  mySwitch.setRepeatTransmit(15); // Set number of transmission repetitions.


}

void loop() {

  wemoManager.serverLoop();
}

void ChristmasLightsOn() {
  Serial.println("Christmas Lights switched ON ...");
  digitalWrite(GreenLED, HIGH);
  digitalWrite(RedLED, LOW);
  mySwitch.send("000001000101010100110011");

}

void ChristmasLightsOff() {
  Serial.println("Christmas Lights switched OFF ...");
  digitalWrite(RedLED, HIGH);
  digitalWrite(GreenLED, LOW);
  mySwitch.send("000001000101010100111100");

}

It's ok, it is now working.

Could you let me know what it was that fixed this issue?
I’m having the same problem with a mkr wifi 1010, and I wonder if something that you did could help me.

(see Alexa fails to discover mkr1010 on wifi )

Thanks!
