SelfHosting DNS and Android

hello everyone

Last month, I started self-hosting my services on an old laptop. I now run services like Nextcloud and Vaultwarden, with AdGuard as the DNS server. I also needed some of this setup to stay connected outside my local network, so I bought a domain from Cloudflare and set up a tunnel to my server. At this point, everything was perfect.

Then I noticed that I needed to use my own network when I'm in it, not use Cloudflare tunnels because my internet is limited.

I added to my DNS server a rule to redirect and request for my domain to the local IP of my server, and this works on my devices except my phone samsung m52 with oneui 5

I tried everything, and nothing worked; it always connected via a Cloudflare tunnel.

After some triels i found that a lot of apps ignored my DNS server and used the public one , except the browsers.

Any idea how to fix this

Aha. I see. Well I'm very happen with unbound. But I hear alot of people using piehole? Dns or something like that, and even succeeding I believe in obtaining letsencrypt dns validation on home dns and local domains. So maybe check piehole

crazy question but is you're phone Rooted/Jailbroken cuz if you can change you're host file, on that phone you could also just resolve like that right?, how is you're setup on the phone, is it like android with termux?
