Alexa can't find the new devices

[woohoo-arr]

Hello, I'm trying to make Alexa discover the devices of the ESPAlexa Basic Sketch, but Alexa don't find any new device.

I'm using the following devices and libraries:

• Library Espalexa by Christian Schwinne, version 2.7.0
• ESP32 38P (https://pt.aliexpress.com/item/1005001636295529.html?spm=a2g0o.order_list.order_list_main.5.1e73caa4W3Bu5u&gatewayAdapt=glo2bra)
  (I have tryed to use the NodeMCU V3 ESP8266, but without success too.)
• Echo 4th generation

At the serial monitor I get this information (I included the #define ESPALEXA_DEBUG command at the sketch):

At the http://[eps-ip]/espalexa I get the following data:
Hello from Espalexa!

At the http://[eps-ip]/api/api/lights I get the following data:

At the Alexa app I'm trying to discover the new devices at the Devices -> + -> Add Device -> Others -> Wi-Fi -> Discover Devices

I tried to reboot my Echo several times, downgraded the Espalexa to the version 2.4.0 (I saw some people saying that with this version is working), but nothing is working for me.

I don't know more what can I do, can someone help me?

Best regards,
André
