Wireguard+ adguardhome not working

hello everyone, I've been trying to configure wireguard+adguard home for a week. If everything stops working, that is, on my local network I use adguard and everything works correctly. Likewise, if I connect my phone through wireguard the tunnel works and I can access the local resources, but if I try to navigate I can't, I have set it to mobile as dns the internal ip of adwardhome and with the tunnel established there is ping, but I don't browse, if I change the dns for example to 8.8.8.8 I can browse, but I lose adguard home, any idea why else can I review? I have omv 7 on a Raspberry pi 4 and wireguard and adguard home through docker. all the best

Thank you very much, with the plugin it works perfectly, you don't know how much I appreciate it, I've been busy for weeks.

All the best
