Hello @CJ007 and welcome to the community,

You provided few wording for a relative complex subject. Need to provide more details on you environment: which board? which middleware are you using? LWIP? with without RTOS? etc etc ..

See the tips on how to post a thread.

PS: see this article on How to create a project for STM32H7 with Ethernet and LwIP stack working

    Hello @CJ007,

    Please ensure that your PC and the board are on the same network and subnet.

    Additionally, verify that the static IP, subnet mask, and gateway are correctly set in your code.

    You can find helpful examples at the following link: STM32CubeH7/Projects/NUCLEO-H723ZG/Applications/LwIP at master · STMicroelectronics/STM32CubeH7
