If a domain from the config never gets an IP, the updates.json stays empty (ip": "",), If I start ddns-updater it registers that empty IP as an error and shuts down. I have to delete the updates.json before I restart ddns-updater.

TLDR: blank IPs in updates.json crash the app.

  1. Is this urgent: No
  2. DNS provider(s) you use: Cloudflare / google
  3. Program version: Running version latest built on 2021-12-04T21:55:55Z (commit fa15abb)
  4. What are you using to run the container: docker, Synology
  5. Extra information (optional)

Ditto... IP is empty: IP 1 of 1 for record {"domain":"r---com","host":"@","ips":[{"ip":"","time":"2023-11-19T00:28:25.40830184-05:00"}]}

Running in Truenas.

    }
  ]
}

On GoDaddy, the IP is set to 127.0.0.1

admin@truenas[.../ddns-updater/volumes/ix_volumes/data]$ nslookup

r---.com
;; communications error to 8.8.8.8#53: timed out <----- Is this the problem?
Server: 8.8.8.8

Non-authoritative answer:

I've replace all of my actual domains with "r---.com"

@semuhphor commented on GitHub (Nov 19, 2023):

Ok .... So I fixed it.

The problem was in the updates.json file. The IP address in the updates.json file must match the A record in your DNS manager. I had read somewhere that if the A record was set to 127.00.1, it would work, but that's not the case. I reset it to my current IP addres (whatismyipaddres.com) and it works like a champ.

The file is /mnt/Main/ix-applications/releases/ddns-updater/volumes/ix_volumes/data/updates.json.

The contents are:

{
  "records": [
    {
      "domain": "r---.com",
      "host": "@",
      "ips": [
        {
          "ip": "173.---",
          "time": "2023-11-19T17:56:44.336197227-05:00"
        }
      ]
    }
  ]
}
