### Issue Details

#### How to reproduce:
- DNS Protection is enabled
- AdGuard DNS DNS-over-TLS is selected
- `IPv6 filtering` option is enabled in Low-level settings

1. Connect via Vpn method and activate protection.
2. Сheck adguard dns on [adguard.com/test.html](https://adguard.com/test.html) and usability of apps (mobilism, easy to notice)
3. Switch over to automatic proxy mode
4. Check adguard dns on [adguard.com/test.html](https://adguard.com/test.html) and usability of mobilism again

### Expected Behavior

As dns is enabled in both mode, the adguard check page should detect adguard's dns in both mode apps like mobilism.
And apps should be able to use proper connection in any mode.

### Actual Behavior

Butt it fails to detect dns while in automatic proxy mode leading to no effect in blocked sites.
Also, the apps constantly loses usability due to lost or connection problems which is very easy to notice on forum apps like mobilism.
