Same problem here. I want to use the DHCP server of Adguard because my provider modem doesn’t supporrt setting dns server in DHCP. I have set static IP-address in Networksetting of Home Assistant but Adguard keeps complening :
“In order to use DHCP server a static IP address must be set. AdGuard Home failed to determine if this network interface is configured using a static IP address. Please set a static IP address manually.”
