Because AdGuard Home is so effective, it will occasionally block a tracker that a legitimate website relies on to function. When this happens, you need to "whitelist" the domain so traffic can flow again.
Overview
If you click a link and your browser says "Server Not Found" or "DNS_PROBE_FINISHED_NXDOMAIN", and it only happens when you are on your home Wi-Fi, AdGuard is doing its job. You just need to tell it to make an exception.
Step 1: Identifying the blocked domain
The hardest part is figuring out exactly which invisible background URL was blocked. AdGuard's Query Log makes this easy.
Try to load the broken website or app on your phone.
Immediately log into the AdGuard Home dashboard on your computer.
Click on Query Log in the top menu.
You will see a live, second-by-second list of every website your network is trying to access.
Look for the entries highlighted in red with a "Blocked" status. The timestamp should perfectly match when you tried to load the app.
You will usually see a URL that looks like a tracking server, e.g., api.segment.io or metrics.hulu.com.
💡 Tip: If your network is very busy, you can use the search bar at the top of the Query Log to filter by the IP address of the device that is having the issue.
Step 2: Unblocking (Whitelisting)
Once you spot the blocked domain causing the issue, you can unblock it instantly.
Hover your mouse over the red blocked entry in the Query Log.
A button labeled Unblock will appear. Click it.
Try loading the website or app on your device again. It should work immediately.
If you prefer to manage your whitelist manually, you can go to Filters > Custom filtering rules. The "Unblock" button simply adds a line here with @@ in front of it (e.g., @@||metrics.hulu.com^).
Handling Google Shopping links
The most common complaint with network-wide ad-blocking is that clicking the sponsored "Shopping" links at the top of Google search results results in a blocked page.
This happens because Google Shopping links route through googleadservices.com to track the click before redirecting you to Target or Amazon.
If you want Google Shopping to work:
Go to Filters > Custom filtering rules.
Type this exactly: @@||www.googleadservices.com^
Click Apply.
⚠️ Warning: Whitelisting googleadservices.com will allow Google to track your clicks on sponsored links. You are trading a bit of privacy for the convenience of using Google Shopping.
