I am very new this and am having trouble getting Alexa to discover my devices.

I am a retired gentleman and my expertise and knowledge is fairly basic.

The url for the my espalexa reports;

Hello from Espalexa!

Value of device 1 (White LED): 0 (Dimmable light) Value of device 2 (Blue LED): 0 (Dimmable light)

Free Heap: 48784 Uptime: 21966

Espalexa library v2.4.7 by Christian Schwinne 2020

However, the Alexa app does not find them. There are 3 Alexa Dots on my network plus a Phillips Hue hub and various other devices.

my code is below and compiles and uploads fine.

Your Debug information is below. I have deleted hundreds of the same "Got UDP" statements to make the report shorter.
