DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "2q3bjpoq4l2lnv9ins106rd75jb4qve9" between the hashed NSEC3-owner "2q39t3d5qcp9v07pjo6vvaaks6hemtlb" and the hashed NextOwner "2q3bmkng6gdbq4ssf8ec0321jfum7ngk".

7. Comments


1. General Results, most used to calculate the result

Aname "adamgurysh.com" is domain, public suffix is "com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services"
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

2. DNS- and NameServer - Checks

AGood: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: ns-1106.awsdns-10.org,ns-1670.awsdns-16.co.uk,ns-18.awsdns-02.com,ns-593.awsdns-10.net
AGood: Nameserver supports TCP connections: 8 good Nameserver
AGood: Nameserver supports Echo Capitalization: 8 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 8 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 8 good Nameserver
Nameserver doesn't pass all EDNS-Checks: ns-18.awsdns-02.com: 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://adamgurysh.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 35.173.247.213
500

Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 500 - 599, Server Error. Creating a Letsencrypt certificate via http-01 challenge can't work. 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
