Hello @ZainFan ,

by costume board I mean is this a Custom PCB that you are using this is not a board provided by ST so you need to make sure that you are rooting the correct pins to the PHY interface are the same (check pinouts in the Ethernetif.c to look for changes as the example you put don't use the same PHY. also make sure you are using the correct lan8720.c file.

Hello, @STea 

I have the same problem. The development board is also STM32F407ZGT6 + LAN8720. Using the httpd.c file to configure the webServer, I can ping the network, but after entering the IP configured for the PHY locally, the webpage cannot return resources, and afterwards I can no longer ping.
