DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "sre6m40udrqev5cjk2o62bf0rck968qc" between the hashed NSEC3-owner "sre5otdmb5bpjde5ue79to0h0178ade8" and the hashed NextOwner "sre6qo2qcdumfj5lmg89dbivpgcikt58". So the parent zone confirmes the not-existence of a DS RR.

DS-Query in the parent zone sends valid NSEC3 RR with the Hash "ck0pojmg874ljref7efn8430qvit8bsm" as Owner. That's the Hash of "com" with the NextHashedOwnerName "ck0q1gin43n1arrc9osm6qpqr81h5m9a". So that domain name is the Closest Encloser of "3doptimizer.com". Opt-Out: True.

Wrong redirect one domain http to other domain https. First redirect to https without new dns query, so the server can send the HSTS header. That's fundamental using HSTS (Http Strict Transport Security). First step: Add correct redirects http ⇒ https. Perhaps in your port 80 vHost something like "RewriteEngine on" + "RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]" (two rows, without the "). Don't add this in your port 443 vHost, that would create a loop. Then recheck your domain, should be Grade C. There is the rule to select one https version as preferred version.

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 supports GZip.
https://3doptimizer.com/ 138.68.75.209
200

Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.
https://3doptimizer.com/ 138.68.75.209
200

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
https://3doptimizer.com/ 138.68.75.209
200

Warning: Https connections (Standard Port 443) found without support of the http/2 protocol via ALPN. Http/2 is the new Http-Version (old: http 1.1) with some important new features. Update your server software so http/2 is available. Only one TCP-connection per Server (that's a performance boost), Header-Compression and Server Pushs are available. Domain Sharding and Inline-CSS/Javascript shouldn't used with http/2.
https://3doptimizer.com/ 138.68.75.209
200

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.: 13 script elements without defer/async.
AGood: All CSS / JavaScript files are sent with GZip. That reduces the content of the files. 22 external CSS / JavaScript files found
AGood: All images with internal compression not sent via GZip. Images (.png, .jpg) are already compressed, so an additional GZip isn't helpful. 34 images (type image/png, image/jpg) found without additional GZip. 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. 21 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 1 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 22 complete.
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 61 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, 61 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: Some img-elements have a valid alt-attribute.: 33 img-elements found, 13 img-elements with correct alt-attributes (defined, not an empty value).
Wrong: img-elements without alt-attribute or empty alt-attribute found. The alt-attribute ("alternative") is required and should describe the img. So Screenreader and search engines are able to use these informations.: 20 img-elements without alt-attribute, 0 img-elements with empty alt-attribute 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
