Samsung S10+ will not use Pi-hole for DNS

The issue I am facing:
Hello. I set up the Unbound DNS service.
When I use my Windows 10 desktop, it works perfectly.
I wanted to do the same on my Samsung S10+ in Wi-Fi mode. I disabled my Data connection, turned on my WI-FI connection, entered a static IP address and 2 IP addresses for DNS1 and DNS2, and activated my Wi-Fi again.
I found that the DNS servers were not solicited, even when i turned them off.
I used a test with ipleak.net and did the test with Edge, Chrome and Firefox after i cleaned the caches. I even did a test with 2 different DNS1 and DNS2 IP addresses than my DNS servers, it didn't change anything.
Has anyone encountered the same problem, thank you

Details about my system: 2 Raspberry servers, with PI-Hole and Unbound activated, following the installation doc.

What I have changed since installing Pi-hole: nothing

This is not an unbound issue, and not a Pi-hole issue. When one client cannot connect to Pi-hole while others can, the problem lies in the client. In your case the Samsung 10+.

I have changed the title of this post accordingly.

Is private dns on?

Not useful for Wi-Fi, you can't use ip address within a private dns, but only domain names.
I think my Smartphone Samsung is the problem, and wanted to know if someone had the same concern , thx a lot

Please expand on this. Is private DNS on or off on the device?

Hello, private DNS is off.
But :
1/ i did my tests with private DNS off or Automatic
2/ I used 2 Samsung smartphones : S10+ and S8
I had the same results, as explained above : it works perfectly with Windows 10, but it doesn't work with the 2 mobiles

One way is to assign a staticIP in the router for the phone. Once you have that new static ip that you assigned (e.g 192.168.1.155), then you should go to setting in your phone, Connections, Wi-Fi, and in the Wifi name (selecting it) go to settings (the gear at the right). Once in there, In Advanced, go to IP settings, select Static and complete Ip address with the static ip you have made, and in DNS1 and DNS 2 put the ip of the pi.hole. Trust me it works, i have a S10

Thank you for the answer, no problem, i trust you :grinning:, i did all that steps before.
Just solved the concern => i turned off IPV6 on my router, and set "do-ip6" and "prefer-ip6" to "no" within unbound.conf. Thx to all
