ddns-updater Bug: Domain update status 'Unset' when it exists in system hosts file

trafficstars

TLDR: When the domain exists in /etc/hosts the domain status gets stuck on 'Unset', and is not updated when using binary on Linux

Is this urgent: No
DNS provider(s) you use: OVH & Custom
Program version: 2.9.0 (commit 78f30614b1d085ef6bfbfce92b0e45ca0204f42a)
What are you using to run the container: N/A, using the binary on Linux
Extra information: When the domain entry is removed from /etc/hosts everyting works as expected and the ip is updated after restarting the binary.
To replicate make sure updates.json is empty. Also tested the Windows, MacOS/Darwin versions and Docker, and these are not effected.

I had the same issue with a persistent unset status using docker and qmcgaw/ddns-updater:v2.9.0 I temporarily fixed it by using an older version.

I have the same issue. I was working fine some weeks ago

I'm also having the same issue on v2.9.0. Downgrading to v2.8.2 did not fix it.

Mar 22 '25 18:03 jrmagers

Same here with Docker latest, v2.8.2 and v.2.8.

Mar 25 '25 23:03 pulsar895

I was able to fix this by setting network_mode: bridge in my docker-compose.yml file. Previously I was specifying a docker network.

  ddns-updater:
    image: qmcgaw/ddns-updater:latest
    container_name: ddns-updater
    hostname: ddns
    network_mode: bridge
    ports:
      - 8000:8000/tcp
...

Mar 26 '25 00:03 jrmagers

No change for me with network_mode: bridge

edit: I fix my problem by using --env RESOLVER_ADDRESS=193.110.81.9:53. It's a local DNS issue on my side.
