Ads escaping Pi-Hole

[mcnaveen]

Expected Behaviour:

Ads should be blocked when pi-hole is active.

Actual Behaviour:

I think the ads are escaping somehow. I saw Google Ads even while Pi-hole is active.

I have set my Raspberry Pi as DHCP Server.

I managed to take all the screenshots

Total Number of Request and Queries blocked

Most of the Queries are answered by Router

Here I set my Router IP as Upstream DNS

I have enabled Conditional Forwarding too

I don't know what is causing the issue. Blocked Queries are still the same from the past 5 hours

From the client on which you are seeing ads, what are the outputs of the following commands from the terminal or command prompt on that client:

nlsookup pi.hole

nslookup flurry.com

Also, please send us the token generated by

pihole -d

or do it through the Web interface:

Were these commands run from the terminal of the device that is running Pi-hole? If so, please re-run them from a different client.

Nope, These commands are from Client Devices. Not from Pi-hole.

Sorry, Apache is running on client device. I didn't notice that.

Here is the New one after stopping apache service

ninja@softinttech:~$ nslookup pi.hole

Ok These outputs show that Pi-hole is the DNS server for that device and is blocking domains.

Where are you seeing ads? Can you provide a URL and screen capture (you can paste the image directly into a reply on this forum).

Also, these tools can help you pinpoint the source of ads:

How do I determine what domain an ad is coming from?

Block ads or fix broken sites This FAQ is written in the context of finding out how to block an ad that isn't blocked automatically, but the same steps can be used to troubleshoot issues with sites that don't function properly. An example is that sometimes certain payment gateways try to collect metrics on the sale, but these domains are blocked by Pi-hole, so the payment cannot be processed. Also, some links send you through several referrers and if one of them is blocked, you may land on a …

and I blocked TikTok Domains, Till yesterday when TikTok opened it shows Internet Connectivity Blocked. But now it's not blocking those domains.
