| 1. General Results, most used to calculate the result |
| A | name "webernet.spdns.org" is domain, public suffix is "spdns.org", top-level-domain-type is "generic", tld-manager is "Public Interest Registry (PIR)"
|
| A | Good: All ip addresses are public addresses
|
| A | Good: No asked Authoritative Name Server had a timeout
|
| A | DNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
|
| A | https://nc-webernet.spdns.org
| https://nc-webernet.spdns.org/login
| Correct redirect https to https
|
| A | Good: destination is https
|
| A | Good - only one version with Http-Status 200
|
| A | Good: one preferred version: non-www is preferred
|
| A | Good: every cookie sent via https is marked as secure
|
| A | Good: every https has a Strict Transport Security Header
|
| A | Good: HSTS has includeSubdomains - directive
|
| A | Good: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
|
| B | Warning: HSTS max-age is too short - minimum 31536000 = 365 days required, 15768000 seconds = 182 days found
|
| E | http://webernet.spdns.org/ 91.16.46.157
| https://nc-webernet.spdns.org
| Wrong redirect one domain http to other domain https. First redirect to https without new dns query, 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.
|
| M | https://webernet.spdns.org/ 91.16.46.157
|
| Misconfiguration - main pages should never send http status 400 - 499
|
| N | https://webernet.spdns.org/ 91.16.46.157
|
| Error - Certificate isn't trusted, RemoteCertificateNameMismatch
|
| R | http://webernet.spdns.org/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 91.16.46.157
| https://nc-webernet.spdns.org.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
| Redirect to not existing domain
|
| 2. Header-Checks (Cross-Origin-* headers are alpha - started 2024-06-05) |
| 3. DNS- and NameServer - Checks |
| A | Good: Nameserver supports TCP connections: 1 good Nameserver
|
| A | Good: Nameserver supports Echo Capitalization: 1 good Nameserver
|
| A | Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 1 good Nameserver
|
| 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 |
| https://nc-webernet.spdns.org.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
|
| Fatal: Check of /.well-known/acme-challenge/random-filename redirects to not-existing domain. Creating a Letsencrypt certificate via http-01 challenge can't work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
|
| A | Good: 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
