DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "t7vk9qd2fqu5631hdvj3hrajgrch6ffb" between the hashed NSEC3-owner "t7vjuhav2mhndnj5tfje8oggdq2eqn95" and the hashed NextOwner "t7vneq8blhepqat5781nljql8jog86ha". 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 "sfblg7nfatq81cqjgt5q91bqs3h9v6nd" as Owner. That's the Hash of "fr" with the NextHashedOwnerName "sfbn9rjnnuevsb0gner878n1gn41d23i". So that domain name is the Closest Encloser of "zinabfs.fr". Opt-Out: True.

7. Comments


1. General Results, most used to calculate the result

Aname "vikunja.zinabfs.fr" is subdomain, public suffix is ".fr", top-level-domain is ".fr", top-level-domain-type is "country-code", Country is France, tld-manager is "Association Française pour le Nommage Internet en Coopération (A.F.N.I.C.)", num .fr-domains preloaded: 3472 (complete: 244198)
AGood: All ip addresses are public addresses
Warning: Only one ip address found: vikunja.zinabfs.fr has only one ip address.
Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: vikunja.zinabfs.fr has no ipv6 address.
AGood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: non-www is preferred
AGood: No cookie sent via http.
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
Bhttps://vikunja.zinabfs.fr/ 128.140.106.157

https://puzzledust/
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.

Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are the same. So that domain doesn't require Server Name Indication (SNI), it's the primary certificate of that set of ip addresses.: Domain vikunja.zinabfs.fr, 1 ip addresses, 1 different http results.

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
