STM32H743 as a client fails in handshake with server at Server Hello using LWIP, mbedTLS and FreeRTO

[MHana.1]

Hello,
I'm using STM32H743 to send and receive REST API. I'm using FreeRTOS, LWIP and mbedTLS to communicate with server. I have the same application working WELL using STM32F765 with MCAL layer of course modified to STM32F7 but using H7 I can see this error "Unknown Record Type" when fetching input and reading input record. I tried solutions like optimizing cipherSuite but was not useful.

Here is the log:
