DS-Query in the parent zone sends valid NSEC3 RR with the Hash "08kei6j2cl2j34ni78ki3qu9r3lrn0ia" as Owner. That's the Hash of "citjamf.cit.nih.gov" with the NextHashedOwnerName "08mev4su48k8si0ag1osc0hrleodo1jn". So that domain name is the Closest Encloser of "www.citjamf.cit.nih.gov". Opt-Out: False.

The ClosestEncloser says, that "*.citjamf.cit.nih.gov" with the Hash "qappr8avm9pb3qenjgo846thjc0qnbah" is a possible Wildcard of the DS Query Name. But the DS-Query in the parent zone sends a valid NSEC3 RR With the owner "qanrmjvr9t7o8192qsfhepgbe4d0tapd" and the Next Owner "qarnlhdr54kn38js27ohd19e9bcntf3e", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion. Opt-Out: False.

7. Comments


1. General Results, most used to calculate the result

Aname "citjamf.cit.nih.gov" is subdomain, public suffix is ".gov", top-level-domain is ".gov", top-level-domain-type is "sponsored", tld-manager is "General Services Administration Attn: QTDC, 2E08 (.gov Domain Registration)", num .gov-domains preloaded: 5117 (complete: 270180)
AGood: All ip addresses are public addresses
Warning: Only one ip address found: citjamf.cit.nih.gov 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: citjamf.cit.nih.gov has no ipv6 address.
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.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)

Error - Certificate isn't trusted, RemoteCertificateNameMismatch
OOld connection: SHA1 as Hash Algorithm is deprecated. Switch to SHA256 or SHA384. If your certificate has SHA256, first check your domain via ssllabs.com and update weak Cipher Suites. Forward Secrecy support is required. The part "Cipher Suites" should have a preference. First Cipher Suite with SHA instead of SHA256 or higher - that's the problem, change that. If that doesn't help, check if there is an old Firewall / router or something else, that supports only SHA1. Update that component.
XFatal error: Nameserver doesn't support TCP connection: nihblox5.nih.gov / 137.187.10.155: Timeout
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 citjamf.cit.nih.gov, 1 ip addresses, 1 different http results.
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.citjamf.cit.nih.gov

4. Content- and Performance-critical Checks

-14

Fatal: Check of /.well-known/acme-challenge/random-filename has a timeout. 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.
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
