Aname "mastodutch.com" is domain, public suffix is ".com", top-level-domain is ".com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .com-domains preloaded: 85538 (complete: 220007)

AGood: No asked Authoritative Name Server had a timeout
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: www is preferred
AGood: No cookie sent via http.
AGood: HSTS has preload directive
Warning: HSTS preload sent, but not in Preload-List. Never send a preload directive if you don't know what preload means. Check https://hstspreload.org/ to learn the basics about the Google-Preload list. If you send a preload directive, you should **immediately** add your domain to the HSTS preload list via https://hstspreload.org/ . If Google accepts the domain, so the status is "pending": Note that new entries are hardcoded into the Chrome source code and can take several months before they reach the stable version. So you will see this message some months. If you don't want that or if you don't understand "preload", but if you send a preload directive and if you have correct A-redirects, everybody can add your domain to that list. Then you may have problems, it's not easy to undo that. So if you don't want your domain preloaded, remove the preload directive.

4. Content- and Performance-critical Checks

AGood: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).

AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
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

11. Html-Content - Entries

No Html-Content entries found. Only checked if https + status 200/401/403/404

 

12. Html-Parsing via https://validator.nu/ / https://validator.w3.org/nu/ (started 2024-09-28, 09:00, alpha)

  Unfortunately, there are differences between the first used validator.nu and validator.w3.org/nu/ - switched to validator.w3.org/nu/. Looks like some error messages (link - fetchpriority attribute) of validator.nu are obsolete, not seen in the w3.org-version and not found in the current specification: link may have a fetchpriority attribute.

Small Code update, wait one minute

 

13. Nameserver - IP-Adresses

Required Root-climbing DNS-Queries to find ip addresses of all Name Servers: nico.ns.cloudflare.com, paris.ns.cloudflare.com
