Can't work out why ddns-updater container is unhealthy

[mpfl]

Fired up ddns-updater today for my proxied Cloudflare setup. The container is reporting as unhealthy but I can't find any issues in the logs. Changed log level to debug and still couldn't find anything there.

How can I start to diagnose the issue?

What are you using to run the container?

Also what's the healthcheck defined when you docker inspect ddns-updater?

Aha! docker inspect gave me the information I needed to go back to the documentation and realise that I had left the vital "proxied": true from my config.

Problem existed between keyboard and chair.

Thanks for the tips! That's what I get for not RTFM.
