Adguard doesn't work when client use incognito/private mode while browsing

It functions properly when using a regular browser, but once I switch to private/ incognito mode, nothing happens. I conducted some tests, such as visiting websites that are supposed to be blocked, but they aren’t blocked and open normally. Although AdGuard’s general statistics indicate that it blocked the site, in reality, the website opens as usual.

Can you give us more details?
Which Adguard do you use?

  • AdGuard Home
  • AdGuard Browser extensions
  • AdGuard Mobile App
  • AdGuard DNS

How did you configure it?

Many browsers have options to use extra “private” DNS services and even DNS-over-HTTPS, which will circumvent your setup.
This is a browser setting and can not really be handled from AdGuard.

Which browser.
