Alexa doesn't find devices, with esp32, please help.

[ReptilMagico]

_This is my code, everything is just fine. But when i tell alexa to search for devices, she literally can't find nothing, i've tried the debug method too, but i don't understand the problem. Please, @Aircoookie , you're an amazing programmer i know you can help me with this problem, let me know if there is any solution.

Everything boots just fine, my code is basically for turning on basic lights, with 8 relays.

My Alexa is a 2nd generation DOT._

Assuming the same issue as me #142

Please include #define ESPALEXA_DEBUG and your serial monitor output! Hopefully, @Aircoookie Responds to us.

I solved it! Well i believe it was just luck but i restarted my alexa dot and the arduino ide, then upload it again and it worked!

Same with me!!! Thank you. Dumb of me to not think of that haha.
