hi its been months since i started my journey with the ethernet port i need to communicate via UDP to a pc to get data from the board and send

i succeeded some times where some of my projects worked for a while then stopped

sometimes the board doesnt ping at all

the problem is that i work on this project on and off not continuously so i tend to forget what i did every last time now it's not pinging or nothing

i tried following the  https://controllerstech.com/stm32-ethenret-2-udp-server/  tutorial and it just worked then stopped

if any of you succeeded with the udp server please help and thanks in advance
