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 "5agtr1tfc1pc8rek878bu3qlrhrjd3h2" between the hashed NSEC3-owner "5adqraj538fhvl2tv6qia9rlsrd68j12" and the hashed NextOwner "5ahu061jb1o2uu85a40i5r9shm3qtjd5". 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 "9nos90sudpc503ec1bd8pem2ocmvhduk" as Owner. That's the Hash of "link" with the NextHashedOwnerName "9nu518hoc58uuh0tdvfskaqogbaukqi4". So that domain name is the Closest Encloser of "zlkrs.link". Opt-Out: True.

1. General Results, most used to calculate the result

Aname "zlkrs.link" is domain, public suffix is ".link", top-level-domain is ".link", top-level-domain-type is "generic", tld-manager is "Uniregistry, Corp.", num .link-domains preloaded: 224 (complete: 244198)
AGood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
XFatal error: Nameserver doesn't support TCP connection: ns01.trs-dns.net: Timeout
BNo _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.zlkrs.link

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: cloudflare.com

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: 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
