Wi-Fi DHCP Timeout

Question

Hello nordic community, 
 i have custom board that have nRF5340 and nRF7002, our requirement is to use wifi every 5 minutes (connect send data and disconnect) but randomly getting DHCP timeout error mentioned below, and also tested after increasing DHCP event time to 30 second but still is not working, E: wait_for_next_event: Timeout waiting for Wi-Fi DHCP -> -11 
 Is there anything i am missing from driver side to solve this issue. 
 i am Using nRF Connect SDK v2.7.0.

After adding net_if_up(net_if_get_default()); before wifi connect request and adding net_if_down(net_if_get_default()); after wifi disconnect

after adding this two functions i didn't reproduce the issue

Thanks for your time
