recv failed with errno 134 using nrf5340dk with W5500 shield

Question

Hello,

I am currently working with the nRF5340DK and the W5500 shield. Both work perfectly when using the dhcpv4_client application. However, when I attempt to use the recv function after creating a socket, it fails and returns a length of -1, with an error code of 134 (not supported), and I’m unsure how to resolve the issue.

Here's my main.c :

/* Networking DHCPv4 client */
