Problem When using docker pihole container as the sole DNS on the network, other containers cannot resolve DNS. Symptoms Other containers unable to resolve DNS using nslookup in other containers gives erros stating something like ;; reply from unexpected source: 172.17.0.1#53, expected 192.168.1.…

I had the very same problem: all devices in the network including the raspberry pi itself could use the pihole as the new DNS server... except inside the other containers running on the raspberry pi. Your solution - using the local IP address of the raspberry pi - worked! I don't know how you manag…

Any thoughts as to get this working while using --net=host? Found It - need to use listen-address and bind-interfaces[1] to force Pihole on the specific IP/Interface. Now containers can successfully resolve internally. [1] Make pihole-FTL bind only on certain IPs [v4.0] - #4 by deHakkelaar

Thank you. This solved my problem why Nextcloud and other containers couldn't resolve all addresses.

Thank You so much. This was driving me crazy and your solution worked perfectly.

Thanks! Saved the day, literally :slight_smile:

Thanks a bunch! This really should be documented somewhere.

THIS SOLVED MY ISSUES AS WELL!! :slight_smile: ... did you end up changing "53:53/tcp" to "192.168.1.2:53:53/tcp" as well?

Thanks for this! it appears 53/tcp doesn't need to be binded to the ip/interface. would love to know more details on why exactly is this happening

The above solution for me is NOT the best.I would like to suggest a solution much easier and with absolutely no editing in any docker-compose.yml. In /etc/resolvconf.conf you just need to enable: nameserver 127.0.0.1 ... as written in this file itself: # If you run a local name server, you …

Thank you 3lder Updated my docker containers last night, including PiHole and for some reason I ended up with this issue. The internal containers could no longer access the DNS port 53 on the host. I am running PiHole with the port exposed to the host. I removed Resolvconf since it could not run …
