7. Comments


1. General Results, most used to calculate the result

Aname "banthon.de" is domain, public suffix is "de", top-level-domain-type is "country-code", Country is Germany, tld-manager is "DENIC eG"
AGood: All ip addresses are public addresses
AGood: No asked Authoritative Name Server had a timeout
AGood: destination is https
AGood: one preferred version: www is preferred
AGood: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):0 complete Content-Type - header (3 urls)
https://www.banthon.de/ 87.150.11.51


Url with incomplete Content-Type - header - missing charset

Missing HSTS-Header
Dhttp://banthon.de/ 137.74.127.233
301
http://www.banthon.de
Wrong redirect one domain http to other domain http. First redirect to https without changing the domain, so no new dns query is required. 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.

3. DNS- and NameServer - Checks

AGood: Nameserver supports TCP connections: 6 good Nameserver
AGood: Nameserver supports Echo Capitalization: 6 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 6 good Nameserver

Nameserver doesn't pass all EDNS-Checks: ns3.domaindiscount24.net / 2607:5300:60:5e1c:198:27:76:32: OP100: ok. FLAGS: ok. V1: ok. V1OP100: ok. V1FLAGS: ok. DNSSEC: fatal timeout. V1DNSSEC: ok. NSID: ok. COOKIE: fatal timeout. CLIENTSUBNET: ok.
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.

4. Content- and Performance-critical Checks

Ahttp://banthon.de/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 137.74.127.233
200

Good: Acme-Check - Answer looks like a correct keyAuthorization - String: Filename + "." + base64url(Thumbprint(accountKey)). So creating a Letsencrypt certificate using that integrated solution should work. Don't use another client (like Certbot). Don't mix integrated solutions with own ACME-clients, that may not work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
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
