dns over tls doesn't use ipv6

[Celexi]

Prerequisites

• I have checked the Wiki and Discussions and found no answer

• I have searched other issues and found no duplicates

• I want to report a bug and not ask a question or ask for help

• I have set up AdGuard Home correctly and configured clients to use it. (Use the Discussions for help with installing and configuring clients.)

Platform (OS and CPU architecture)

Custom (please mention in the description)

Installation

Other (please mention in the description)

Setup

On one machine

AdGuard Home version

0.107.48

Action

Replace the following command with the one you're calling or a
description of the failing action:

nslookup isc.org

Expected result

The lookup should go first via ipv6 if that is available before falling back to ipv4. They correctly go via ipv6 first in windows or android.

Actual result

all tls requests are going via ipv4, I have tried both in adguard dns and nextdns so I could see the logs.

Additional information and/or screenshots

My adguard dns is running in hassos as an addon, however I tried installing it on a server just to rule out that was not the root cause, and it still looks up tls requests via ipv4.
