DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "ljk07thheb5k447kvbdkq5511rvpnpee" between the hashed NSEC3-owner "ljjt6kl0882h7n9bib5iu2jr83126218" and the hashed NextOwner "ljk29j2c3e3fu0fdssh1sfj1mj7c9j5i".

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.

AInfo:: 26 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
AInfo:: 26 Queries complete, 26 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
Bad (greater 8):: An average of 13.0 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 2 different Name Servers found: ns43.domaincontrol.com, ns44.domaincontrol.com, 2 Name Servers included in Delegation: ns43.domaincontrol.com, ns44.domaincontrol.com, 2 Name Servers included in 1 Zone definitions: ns43.domaincontrol.com, ns44.domaincontrol.com, 1 Name Servers listed in SOA.Primary: ns43.domaincontrol.com.
AGood: Only one SOA.Primary Name Server found.: ns43.domaincontrol.com.
AGood: SOA.Primary Name Server included in the delegation set.: ns43.domaincontrol.com.
AGood: All Name Server Domain Names have a Public Suffix.
AGood: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
AGood: All Name Server ip addresses are public.
AInfo: Ipv4-Subnet-list: 2 Name Servers, 2 different subnets (first Byte): 173., 97., 2 different subnets (first two Bytes): 173.201., 97.74., 2 different subnets (first three Bytes): 173.201.69., 97.74.101.
AExcellent: Every Name Server IPv4-address starts with an unique Byte.

AGood: Name Server IPv6 addresses from different subnets found.

AGood: Nameserver supports Echo Capitalization: 4 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 4 good Nameserver

AGood: All SOA have the same Serial Number
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.

4. Content- and Performance-critical Checks

AGood: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
AGood: No https + http status 200 with inline CSS / JavaScript found
AGood: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.

Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage. Use "async" if the js file has only functions (so nothing is executed after parsing the file) or is independend. Use "defer" if the order of the scripts is important. All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 1 script elements without defer/async.

Warning: Svg-Images greater 1024 Bytes without internal compression are found. Svg is an Xml-Application, so Compression is required to reduce the size of the file. 2 images (type image/svg+xml, image/x-icon, image/vnd.microsoft.icon) found without compression.
Warning: CSS / JavaScript found without Compression. Compress these ressources, gzip, deflate, br are checked. 2 external CSS / JavaScript files without Compression found - 0 with Compression, 2 complete
AGood: All images with internal compression not compressed. Some Images (.png, .jpg, .jpeg, .webp, .gif) are already compressed, so an additional compression isn't helpful. 96 images (type image/png, image/jpg, image/jpeg, image/webp, image/gif) found without additional Compression. Not required because these images are already compressed
Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 4 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 4 complete.
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 98 image files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 98 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: All img-elements have a valid alt-attribute.: 147 img-elements found.
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
