Pi-Hole blocking behaviour not understandble

[FlippiHimself]

Hi there,

Expected Behaviour:

• Host: Raspberry Pi 4
• Pi-hole version is v5.6 (Latest: v5.6)
• AdminLTE version is v5.8 (Latest: v5.8)
• FTL version is v5.11 (Latest: v5.11)

Problem description:
Ads on websites (like msn.com) or youtube (these AD vids in between) are not filtered out.
This suggest a wrong configuration in my network provoking these problems.

1. Fritzbox configuration:

DNS-Server configuration ( Home network -> network -> ipv4 settings) telling the clients that its still my Fritzbox and nothing changed here:

DNS-Server settings (Internet -> DNS-Server) considering internet-traffic is set up like the following. Here i have set the static IP of the Pi-hole (192.168.178.119) in my network.

2. Pi-hole configuration
As DNS-settings, i am using unbound and this seems to work pretty well as the following command line shows it:

For blocking youtube ads, i have installed under "Adlists" a link copied from sunshine.it. This should help blocking youtube ads (after the description)

As you can see here, Pi-hole is getting traffic and its shown that queries are blocked and so on...

Actual Behaviour:

My understanding
I suppose (after all the videos i have seen and posts i have read...) that ADs like google ads and ads on youtube should be taken in consideration due to the settings i have made.

This is the understanding i have until now: A client request goes first do the fritzbox (192.168.178.1). The fritzbox is redirecting it to the pi-hole (192.168.178.119) which is doing then its job as some DNS settings are set up on Pi-hole.

Here some examples of websites not blocking with ads.

MSN

YAHOO

YOUTUBE

I hope someone can helping me understanding the system and how it workd or even if i have set up something wrong.

Thanks a lot in advance!

Greetings

Pi-hole cannot reliably block YouTube ads, since the ads are served from the same domains as the content. If you block the domains, you interfere with the content. There is a long running thread on this topic.

How do I block ads on YouTube?

Update 2020-10-24 It's not likely that you'll be able to block in-video ads with Pi-hole. For that, you'll need something like uBlock origin for desktop, or vanced for android (Now defunct), This thread has been closed as there is not much more discussion to be had around the topic. Update 2018-11-14 User's have had good success here: I'm updating this top-level post as of 2018-10-16 since a lot of people land here. Blocking ads on YouTube is hit or miss with Pi-hole. The reason for th…

For blocking youtube ads, i have installed under "Adlists" a link copied from sunshine.it. This should help blocking youtube ads (after the description)

This list won't help much, and will typically interfere with content.

As for the msn.com ads, when I visit that site using Pi-hole only as an ad-blocker (no browser add-ons installed to block ads), I see no ads. I do see sponsored content.

These tools can help determine 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 …

In your specific setup instance, you have provided Cloudflare as a DNS server in addition to Pi-hole. This allows clients to bypass Pi-hole.

Why should Pi-hole be my only DNS server?

Reduced Ad Blocking Capability The main reason you should Pi-hole as your only DNS server is that you will see increased performance in the blocking of ads. If you have two DNS servers (Pi-hole and something else), your network clients may not always query Pi-hole for name resolution. If a query happens to be answered from a non-Pi-hole DNS server, your block lists will not apply (since that DNS server doesn't know about them). All Queries Need To Go Through Pi-hole First Since other DNS se…
