Site blocked by AdGuard DNS?

AdGuard DNS, AdGuard’s cloud DNS service, filters ads, trackers and threats for every app on your device. This guide is for the cloud service; if you run your own server, see the AdGuard Home guide.

Updated November 2026. Menus move around between versions: if a label is a little different, look for the closest match.

Signs it’s AdGuard DNS

• “Site can’t be found” errors, or parts of a page missing in every browser on the device.
• It works on another network or with AdGuard DNS switched off on the device.

Find what blocked it

1. Sign in to your AdGuard DNS dashboard and open the Query log.
2. Reload the broken page, then filter to blocked queries and search for the site.
3. The entry shows the rule that matched and the blocklist it came from.

Allow it

• One domain: in your DNS server’s settings, open User rules and add @@||example.com^ (this allows the domain and its subdomains).
• A blocklist that breaks too much: turn it off in the server’s blocklist settings.
• Blocked services, parental control and security settings can also block whole sites. Check them if no blocklist rule matched.
• Restart the browser if the page still fails a minute later. DNS answers are cached briefly.

Good to know

• The AdGuard browser extension and app are separate products with their own rules. If you use those too, see the guide for other blocker extensions.
