Cannot obtain certificates for subdomains about docker-compose-usenet HOT 2 CLOSED

DNS problem: NXDOMAIN looking up A for ombi.robflate.ddns.net indicates a missing A record for that domain I believe. I would hazard a guess and say that the service you're using doesn't support what you're trying to accomplish.

The steps in the README recommend your own domain for the reason that getting it to work with a dynamic DNS provider is not always straightforward (if possible at all), as you've found out. I would strongly recommend purchasing a domain of your own (some TLDs are available for under $1) instead.

As another has observed adding CNAMEs to your DNS record makes it fairly straightforward when using your own domain if you don't have a static IP.

You could change the compose file to use path-based routing instead (eg robflate.ddns.net/ombi etc), but that's not something I intend to implement in the project myself.

Ultimately buying a cheap domain is the path of least resistance.

I ended up doing it with my own domain using the information provided by @wmelani in this post. Certificates are now working correctly. Thanks for your help and for sharing this code.
