lol - I read this timestamp and not this 2024-05-22T

Apologies mate.

Iznobe_D · May 22, 2024, 7:58pm

no problem

CallMeCurious · May 22, 2024, 8:11pm

It's looking out side the local network for resolution ( 80.67.169.12 ).

Do you get a different result if you dig@(your pihole ip) baby ie dig@192.168.1.3 baby

Iznobe_D · May 22, 2024, 8:18pm

this is FDN 's IP servers . i think this is due to the DOH set up .

if i dig my pi's ip :

iznobe@iznobe-PC:~$ dig 192.168.1.132

yes , but it should looks before in cache DNS or as it is write in the dedicated page :

Note:

The order of locally defined DNS records is:

The device's host name and pi.hole

Configured in a config file in /etc/dnsmasq.d/

Read from /etc/hosts

Read from the "Local (custom) DNS" list (stored in /etc/pihole/custom.list)

Only the first record will trigger an address-to-name association.

before searching outside on the external DNS no ?

@CallMeCurious

I think your intention was to ask to run:
dig @192.168.1.3 baby

Details

When you need to add an at symbol (@) inside a command, you need to surround it with backtiks (`), like this:

command `dig @PI-hole_IP domain`

(or just select the command and press CTRL+E)

CallMeCurious · May 22, 2024, 8:30pm

Yes. I was just editiing that.

@Iznobe_D please try dig @192.168.1.132 baby and lets see what you get.

Iznobe_D · May 23, 2024, 10:21am

hi, seems to work with :

iznobe@iznobe-PC:~$ dig @192.168.1.132 baby

So the pihole custom list is working ok.

I'm not familiar with the cloudflared setup but reading through the guide cloudflared (DoH) - Pi-hole documentation it shows a test for it. From the pihole itself the command below and post results please.

dig @127.0.0.1 -p 5053 google.com

That looks correct so the cloudflared service looks to be working. Looking at the pihole webgui, is the upstream server set to custom ipv4 / 127.0.0.1#5053?

Iznobe_D · May 23, 2024, 11:46am

yes ,this is good .

seen in the previous commande :

SERVER: 127.0.0.1#5053(127.0.0.1)

ok , so just re-tested to acces to my server " baby " and now working as excpeted .
Don't know what happened , just done a reboot yesterday night , and now all seems to be fine .

Thanks

CallMeCurious · May 23, 2024, 11:55am

I suspect that one client was connected to a vpn or something like that. It would explain the out of network server that was returned. Either way, glad its working for you.
