Pi-hole slow to load certain sites

Hi,

Pi-hole:

DNS:

IPv4:

IPv6:

Router always assign ULA:

iptables -nvL

ip6tables -nvL

Example ad blocked in 4.29s
https://www.google-analytics.com/analytics.js

also running pihole -r
gives me the following output i think something wrong with FTL sometimes ads are blocked and sometimes they arent

i ve reinstalled it now it tells me that ftl is running but still ~4s

What is the output of :
sudo systemctl status dnsmasq
sudo systemctl status pihole-FTL

And what operating system are you running Pi-hole on ?

Have you seen this post:

There might be some answers there.

You might want to upload a debug log for the developers to look into any possible errors (pihole -g)


Raspberry Pi Zero

RASPBIAN STRETCH LITE
Minimal image based on Debian Stretch
Version: April 2018
Release date: 2018-04-18
Kernel version: 4.14

Yes i've seen the post but i think it didnt helped maybe i missed something or doing wrong i dont know

Someone with a Fritzbox fixed with this:

I dont want to insert the IP Address of my Pi in the router because i dont want to use the adblocker globally.

But there is a IPv6 Tab

whats the difference between Native IPv4-Connection and Native IPv6-Connection in the IPv6-Connection fieldset?

IPv4-Connection is recommended and selected as default:


I've just selected IPv6-Connection to show the hidden options:

Some other IPv6 configuration options (i've enabled ULA):


Default settings:

I've just selected disable DHCPv6-Server to show the hidden options:

here the debug token: ns1nwpysog
today the request was blocked in ~2.15s
not sure why it takes up to ~4s and today its half of the time.

You could disable IPV6 for your internal LAN. As in disable IPV6 on your fritzbox as well as on your Pi.

I think some requests from clients try to resolve via IPV6 and since that is not defined in Fritzbox, it takes a little bit of time, for the request via IPV6 to time-out and fall back to IPV4.

Hmm i can disable it but what do you mean with my IPv6 is not defined?
My FRITZ!Box is telling me that my pi got an IPv6 address and i ve also set the dns server manually on my client to my pi holes IPv6 address so it should use the pi holes dns server.

So you mean using both options (IPv4 and IPv6) may lead to a longer request time because of the time-out (fallback). Running only one option (IPv4 only) should avoid the fallback.
