TLDR: The app install interface and tutorial say "@" should precede the hostname. That doesn't work in my case.

Is this urgent: Yes
DNS provider(s) you use: Duck DNS
Program version: 2.6.0

Running version 2.6.0 built on 2024-02-03T18:53:40.722Z (commit c338c28)
What are you using to run the container: TrueNAS SCALE UI
Extra information (optional)
I struggled setting this up for several days, but it was always "Deploying". It never made sense to me that the Hostname should be preceded with "@". The App seemed to be broken because when I tried to check logs, there was no container listed so I couldn't access logs. Eventually I deleted the app and started over without any "@" in Host field. Voila.

See also the Tutorial, the instructions for entering Host:

It depends on the provider, duckdns "official" (as in, written for the container, not for the truenas setup which I'm not the author of) is at aa12ccc0b9/docs/duckdns.md (L24)

So technically, it should have a "host" set and no "domain" set (since it's always duckdns.org). I'm not too sure how they map the setup in truenas to the json configuration file for this container.

Would you please suggest a change at https://github.com/truenas/documentation/edit/master/content/SCALE/SCALETutorials/Apps/CommunityApps/ddns-updater.md and you can refer this issue for the maintainers of the truenas documentation? Especially since I don't use Truenas 😉 Thanks! 👍

The App seemed to be broken because when I tried to check logs, there was no container listed so I couldn't access logs.

@ is not allowed for the host for duckdns, so the container prints an error and exits, that's why the container is no longer there, and I guess truenas keeps it in a "Deploying" state, since it keeps on exiting as soon as it starts 🤔
