DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "r79upecpofqi98i7leb357ti6akv40ko" between the hashed NSEC3-owner "r79upecpofqi98i7leb357ti6akv40ko" and the hashed NextOwner "r7a0nnm9snch7edj5o2m5fkg2n8c2mua". So the parent zone confirmes the not-existence of a DS RR.

7. Comments


1. General Results, most used to calculate the result

Aname "server.mysteryroom.cz" is subdomain, public suffix is "cz", top-level-domain-type is "country-code", Country is Czechia, tld-manager is "CZ.NIC, z.s.p.o"
Agood: All ip addresses are public addresses
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.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
CError - no version with Http-Status 200
Hfatal error: No https - result with http-status 200, no encryption
Mhttps://server.mysteryroom.cz/ 84.42.237.218
404

Misconfiguration - main pages should never send http status 400 - 499

2. DNS- and NameServer - Checks

AGood: Nameserver supports TCP connections: 2 good Nameserver
AGood: Nameserver supports Echo Capitalization: 2 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 2 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 2 good Nameserver
Nameserver doesn't pass all EDNS-Checks: ns.endora.cz: OP100: no result. FLAGS: no result. V1: no result. V1OP100: no result. V1FLAGS: no result. DNSSEC: no result. V1DNSSEC: no result. NSID: no result. COOKIE: no result. CLIENTSUBNET: no result.
AGood: All SOA have the same Serial Number
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.

3. Content- and Performance-critical Checks

http://server.mysteryroom.cz/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 84.42.237.218
-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.
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
