the mdns is not working for the sample project http_server

Question

I am using the hardware nrf5340-dk/7002-ek I compiled the sample project http_server with CONFIG_SHELL option enabled I connected my board to my wifi network with the wifi command I used wireshark and I was expecting to see mdns from my board but there is no mdns from my hardware I even executed the following commands from my PC but I did not get any response dns-sd -B _services._dns-sd._udp local
dns-sd -B _http._tcp local and I can ping my device from my PC I can see in the source code main.c DNS_SD_REGISTER_TCP_SERVICE(http_server_sd, CONFIG_NET_HOSTNAME, "_http", "local",
 DNS_SD_EMPTY_TXT, SERVER_PORT); and here after my prj.conf #
