To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.
ERROR: Cert does not exist! Please see the validation error above. The issue may be due to incorrect dns or port forwarding settings. Please fix your settings and recreate the container

I’s sure that record A exist with DNS of Cloudflare

You have several problems for azacheo.com: no DNS record found, no DMARC record found, among others.

Also, duckdns.org shows it’s been blacklisted

For your spacetv.duckdns.org, you have 9 problems: DNS record not found; at least one name server not responding in a timely manner; smtp failed to connect, local NS list doesn’t match parent NS list; No SPF records found as TXT. (Record type 99 (SPF) has been deprecated); among other problem. Here’s the link to this:
https://mxtoolbox.com/domain/spacetv.duckdns.org/

Checking your domain spacetv.duck.dns.org, this is the result from DNSLookup.org:
“ALERT: Search Error or Records not Exists.”

You can also run tests at https://www.ssllabs.com/index.html as they will also give you a little more information.
You may want to contact DuckDNS support for a little help to straighten things out before trying to get certificates. It sounds like a lot of “little” things have to be corrected first.
