0 DS RR in the parent zone found



DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "gc73lhuq6dj9oi0l0k09geoac6931ags" between the hashed NSEC3-owner "gc72hitqk5jf4ctjmnhis4u50f499nfr" and the hashed NextOwner "gc7f48roq2jb6v2vjj3utbjbqei9fias". So the parent zone confirmes the not-existence of a DS RR.
Bitmap: NS, DS, RRSIG Validated: RRSIG-Owner gc72hitqk5jf4ctjmnhis4u50f499nfr.co., Algorithm: 8, 2 Labels, original TTL: 900 sec, Signature-expiration: 15.10.2023, 04:19:12 +, Signature-Inception: 15.09.2023, 04:05:51 +, KeyTag 19065, Signer-Name: co



DS-Query in the parent zone sends valid NSEC3 RR with the Hash "ldc0c7m112348qmhs09hokrvkepgubv6" as Owner. That's the Hash of "co" with the NextHashedOwnerName "ldc4j0skeamis1d5g3f6do9con7b145c". So that domain name is the Closest Encloser of "optirank.co". Opt-Out: True.

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.

Fatal: Check of /.well-known/acme-challenge/random-filename is blocked, http connection error. Creating a Letsencrypt certificate via http-01 challenge can't work. You need a running webserver (http) and an open port 80. If it's a home server + ipv4, perhaps a correct port forwarding port 80 extern ⇒ working port intern is required. Port 80 / http can redirect to another domain port 80 or port 443, but not other ports. If it's a home server, perhaps your ISP blocks port 80. Then you may use the dns-01 challenge. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

Creating a Letsencrypt certificate via http-01 validation may not work. Checking the validation file in /.well-known/acme-challenge Letsencrypt prefers ipv6. Two options: Remove your ipv6 / AAAA DNS entry or (better) fix your ipv6, so your webserver handles ipv6 correct. Perhaps add "Listen [::]:80". Don't use <VirtualHost ip-address:80>, switch to <VirtualHost *:80>. If you use IIS, check your bindings. Don't select a single ip address. Use this tool to check your raw ipv6 address. Add your domain name in the "Hostname" - field. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

Fatal: Check of /.well-known/acme-challenge/random-filename has different answers checking ipv6 / ipv4. Ipv6 doesn't have the expected result http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 validation may not work. Checking the validation file in /.well-known/acme-challenge Letsencrypt prefers ipv6. Two options: Remove your ipv6 / AAAA DNS entry or (better) fix your ipv6, so your webserver handles ipv6 correct. Perhaps add "Listen [::]:80".

AGood: Every https result with status 200 supports GZip.

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.

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 CSS / JavaScript files are sent with GZip. That reduces the content of the files. 4 external CSS / JavaScript files found
Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 2 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 2 with Cache-Control max-age too short (minimum 7 days), 2 with Cache-Control long enough, 6 complete.
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 2 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, 2 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
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.: 2 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
AInfo: Different Server-Headers found
