Trying to get certs for GoDaddy domain through DynDNS ddns

I’m trying to get certs for a newly-purchased actual domain I’ve recently purchased. The domain is GoDaddy but the DNS is provided by DynDNS. There’s a 301 redirect from the GoDaddy domain to the DynDNS host. Certs on the DynDNS host have worked before, so I’m thinking the issue is at the GoDaddy end. Not sure what to do here.

My domain is: AND (301 from on GoDaddy to on

I ran this command: certbox --nginx
— names input:,,

It produced this output:

My web server is (include version): nginx 1.14.2

The operating system my web server runs on is (include version): Raspbian Buster

My hosting provider, if applicable, is: n/a - self-hosted

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 0.31.0

DNS resolves the shorter name to IP:
Which is a GoDaddy IP, but there is nothing responding at that IP.
[not on port 80 and not on port 443]

This does NOT appear to be a currently accurate statement:

The authoritative nameservers for are from GoDaddy:

nslookup -q=ns     nameserver =     nameserver =

I just figured out I needed to add a CNAME for www. That works. Certbot now only fails on I’m trying to figure out how to fix that one, but if any tips would be appreciated.

If GoDaddy allows CNAME on APEX (root/entire domain), you can just send the whole thing to the longer name.

Otherwise, you may need to catch the short name with an HTML page and redirect within that.

Added a * CNAME for the root, because GoDaddy is weird. Now I have to wait because I’ve hit the failed verifications rate limit. I’ll check back in an hour.

Agreed but I still don’t see the IP changed:
Both authtoritative nameserver still say

nslookup -q=a
nslookup -q=a

And to make matters worse…
Now the WWW resolves to “empty”

You may need to talk with them (review their docs)…
But I think in order to CNAME an APEX record, you can’t have any other records in that zone (NONE).
Only the single root CNAME entry.

Yeah, I’m seeing that. I’ve solved a very similar problem before in a previous job, but I don’t at all remember how. I’ll need to do some research.
