Ssl_server2 example not working with mbedTLS 2.26.0

Hi,
I am trying to run ssl_server2 and ssl_client2 example from mbedTLS 2.26.0. But i am getting this error when i run ssl_server2

Same thing i have observed with 2.24.0 but when i am running with 2.23.0 it is working fine

Is there any change with this example after 2.23.0 or i need to do something else ?

Thank you,
Shubham
