Why is the ethernet connection unstable?

[non]

I have followed the "https://controllerstech.com/stm32-ethernet-6-http-webserver-simple/" tutorial and have set up some parts on https://github.com/stm32-hotspot/STM32H7-LwIP-Examples for STM32H750B-DK and it works once on WEB SERVER not used FREERTOS. But when I tried the same code It can no longer be used. why not work my project https://drive.google.com/file/d/193mxh5EKTZm_2ccCpIbmdfDcuvyt3WH5/view?usp=share_link

The problem is

1. It takes a long time to connect.

2. Sometimes unable to connect when resetting

I want to know the reason and solution.

Hello @non​ ,

It is recommended to follow the same configuration as in examples provided in STM32CubeH7 package:

e.g. Projects\STM32H743ZI-Nucleo\Applications\LwIP\LwIP_HTTP_Server_Netconn_RTOS
