Hi,
I have used this page to install and configure AdGuard : https://openwrt.org/docs/guide-user/services/dns/adguard-home
All works fine, except that my openwrt (and only my router) can't resolve DNS. I can't use opkg for exemple... But all other computer have no issue... I thinks I have an issue to use DNS from OpenWRT to OpenWRT, do you have some idea to fix it ?
