DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "3h7aih4heakeul1tbo0599qm7vjm9q5k" between the hashed NSEC3-owner "3h7aerqlbr2g580rga9crl4m48adcvvu" and the hashed NextOwner "3h7amj79bccdqlk70i3uvu0sh6l0r1db".

Warning: HSTS preload sent, but not in Preload-List. Never send a preload directive if you don't know what preload means. Check https://hstspreload.org/ to learn the basics about the Google-Preload list. If you send a preload directive, you should **immediately** add your domain to the HSTS preload list via https://hstspreload.org/ . If Google accepts the domain, so the status is "pending": Note that new entries are hardcoded into the Chrome source code and can take several months before they reach the stable version. So you will see this message some months. If you don't want that or if you don't understand "preload", but if you send a preload directive and if you have correct A-redirects, everybody can add your domain to that list. Then you may have problems, it's not easy to undo that. So if you don't want your domain preloaded, remove the preload directive.
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.

3. DNS- and NameServer - Checks

AInfo:: 7 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
AInfo:: 7 Queries complete, 7 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
Ok (4 - 8):: An average of 3.5 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 2 different Name Servers found: ns47.worldnic.com, ns48.worldnic.com, 2 Name Servers included in Delegation: ns47.worldnic.com, ns48.worldnic.com, 2 Name Servers included in 1 Zone definitions: ns47.worldnic.com, ns48.worldnic.com, 1 Name Servers listed in SOA.Primary: ns47.worldnic.com.
AGood: Only one SOA.Primary Name Server found.: ns47.worldnic.com.
AGood: SOA.Primary Name Server included in the delegation set.: ns47.worldnic.com.
AGood: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: ns47.worldnic.com, ns48.worldnic.com

Warning: All Name Servers have the same domain name. If there is a problem with that domain name (or with the name servers of that domain name), your domain may be affected. Better: Use Name Servers with different domain names / different top level domains.: Only one domain name used: worldnic.com
Warning: All Name Servers from the same Country / IP location.: 2 Name Servers, 1 Countries: US
AInfo: Ipv4-Subnet-list: 2 Name Servers, 1 different subnets (first Byte): 162., 1 different subnets (first two Bytes): 162.159., 2 different subnets (first three Bytes): 162.159.26., 162.159.27.

AGood: All SOA have the same Serial Number
AGood: CAA entries found, creating certificate is limited: globalsign.com is allowed to create certificates
AGood: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates

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).
https://www.gelsons.com/ 76.76.21.21
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://vercel.com/

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://vercel.com/
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.
AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
AGood: All script Elements (type text/javascript) and src-Attribute have a defer / async - Attribute. So loading and executing these JavaScripts doesn't block parsing and rendering the Html-Output.
Warning: CSS / JavaScript found without Compression. Compress these ressources, gzip, deflate, br are checked. 1 external CSS / JavaScript files without GZip found - 8 with GZip, 9 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. 7 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. 44 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, 44 complete.
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 143 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, 143 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: Some img-elements have a valid alt-attribute.: 62 img-elements found, 53 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.: 9 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
