Hi!
I have done the following this:
- Make so ping works - OK (https://controllerstech.com/stm32-ethernet-1-connection/)
- Create a simple echo TCP Server - OK (https://controllerstech.com/stm32-ethernet-4-tcp-server/)
These things works. Very good.
But then when I enable HTTPD inside my STM32CubeIDE 1.10.1 and then add a new a fsdata_custom.c or fsdata.c file to my project. Just like they are doing:

https://controllerstech.com/stm32-ethernet-6-http-webserver-simple/
Then it won't work for me. What happens is that when I use my web browser and go to my STM32 address .e.g 192.168.1.15, then I cannot ping any longer to my STM32. But...IF....I ping first, then I can see that the ping stuff is working. But as long I use my web browser to surf into my STM32, then I cannot longer ping my STM32. So I need to restart it. No web site appears at my web browser.
I have tested to debug, but the processor runs and have not fallen into a endles error-loop. So what can be wrong here?
int main(void)

while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
MX_LWIP_Process(); // Without this, I cannot ping.
}
/* USER CODE END 3 */
}
My processor is: STM32F407VGT and I'm using the firmware FW_F4_1.27.1
