ESP does not send the last few bytes to uart from WEB server

Hello all.

I have a web server. And I am sending a post request to ESP.
ESP immediately transfers data to uart (to MCU STM32F429)
The microcontroller uses DMA.
I see that data has been sent to the buffer, but the last few bytes seem to have not been transferred.
If I resend the request, the missing bytes appear in the buffer and a new request is added, which again lacks the last few bytes.
