DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "3gitsp85pi8earriv69nd1drdiv6j8m1" between the hashed NSEC3-owner "3ginlhrgpifn8r643q1vlajm0a4afjnq" and the hashed NextOwner "3giuuaks70tm1fiabnkqdb77rdg4p5o4". So the parent zone confirmes the not-existence of a DS RR.
Bitmap: NS, DS, RRSIG Validated: RRSIG-Owner 3ginlhrgpifn8r643q1vlajm0a4afjnq.org., Algorithm: 8, 2 Labels, original TTL: 86400 sec, Signature-expiration: 22.05.2021, 15:27:10 +, Signature-Inception: 01.05.2021, 14:27:10 +, KeyTag 30453, Signer-Name: org



DS-Query in the parent zone sends valid NSEC3 RR with the Hash "1i870vj5h429vj9pci7ar6e9gki74tr7" as Owner. That's the Hash of "org" with the NextHashedOwnerName "1i87r64gaju4o91mhkbu7i9ekbs7k8ut". So that domain name is the Closest Encloser of "duckdns.org". Opt-Out: True.

CError - no preferred version www or non-www. Select one version as preferred version, then add a redirect https + not-preferred version to https + preferred version. Perhaps in your port 443 vHost something like "RewriteEngine on" + "RewriteCond %{SERVER_NAME} = example.com" + "ReWriteRule ^ https://www.example.com%{REQUEST_URI} [END,QSA,R=permanent]" (three rows, without the "). That should create a redirect https + example.com ⇒ https + www.example.com. Or switch both values to use the non-www version as your preferred version.
CError - more then one version with Http-Status 200. After all redirects, all users (and search engines) should see the same https url: Non-www or www, but not both with http status 200.

2. DNS- and NameServer - Checks

AInfo:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 4 Name Servers.
AInfo:: 2 Queries complete, 2 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
AGood: Some ip addresses of name servers found with the minimum of two DNS Queries. One to find the TLD-Zone, one to ask the TLD-Zone.ns1.duckdns.org (54.187.92.222), ns2.duckdns.org (54.191.117.119), ns3.duckdns.org (52.26.169.94), ns4.duckdns.org (44.242.92.242)
AGood (1 - 3.0):: An average of 0.5 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 4 different Name Servers found: ns1.duckdns.org, ns2.duckdns.org, ns3.duckdns.org, ns4.duckdns.org, 4 Name Servers included in Delegation: ns1.duckdns.org, ns2.duckdns.org, ns3.duckdns.org, ns4.duckdns.org, 4 Name Servers included in 1 Zone definitions: ns1.duckdns.org, ns2.duckdns.org, ns3.duckdns.org, ns4.duckdns.org, 4 Name Servers listed in SOA.Primary: ns1.duckdns.org, ns2.duckdns.org, ns3.duckdns.org, ns4.duckdns.org.

Warning: No CAA entry with issue/issuewild found, every CAA can create a certificate. Read https://en.wikipedia.org/wiki/DNS_Certification_Authority_Authorization to learn some basics about the idea of CAA. Your name server must support such an entry. Not all dns providers support CAA entries.

3. Content- and Performance-critical Checks

https://www.a-nice-box.duckdns.org/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
200

Warning: Not existing ACME-file, but Server sends 200, not 404 or redirect. May be a problem creating a Letsencrypt certificate. Checking /.well-known/acme-challenge/random-filename - a http status 404 - Not Found - is expected. If your server sends content and a http status 200, the validation file (87 bytes, token, dot and the hash of the public part of the account key) may be invisible, so Letsencrypt can't validate your domain. If it is an application that sends this content, perhaps create an exception, so /.well-known/acme-challenge sends raw files. Or create a redirect to another domain and / or port 443, but your Letsencrypt client must support such a solution. Certbot: Use webroot as authenticator - https://certbot.eff.org/docs/using.html Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AInfo: No img element found, no alt attribute checked
AGood: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
