@bigplayer-ai if you select Native - DNS filtering in AdGuard is completely disabled. If you select Native mode, the system DNS is used. What DNS do you use in the system settings?

my custom personal Adguard DNS server, so all the filtering rules and settings happens on the Adguard DNS dashboard...

[maxikuzmin]

@bigplayer-ai so you are using Native mode to use AdGuard DNS server in system settings?

That’s correct

[maxikuzmin]

@bigplayer-ai please specify which DNS address you are adding, and also the path you are adding the DNS to the system settings

@bigplayer-ai any news?

@bigplayer-ai any news?

When installing adguard dns profile it works perfectly fine, but when using the AdGuard application as the system dns it does not work...

most likely the problem is adguard application

@bigplayer-ai you already said that AdGuard DNS doesn't work in Native mode. Please answer my questions:

please specify which DNS address you are adding, and also the path you are adding the DNS to the system settings

When choosing application dns it doesn’t work

When choosing external Adguard DNS profile it works fine, this works just fine:

@bigplayer-ai I see. The profile may not have been installed correctly, try reinstalling the profile for Native mode. Reinstall AdGuard and try again. I have tested your problem on several devices - everything works correctly, the test site passes validation successfully
