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

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).
https://online.kradblatt.de/de/profiles/fa9830ee2805-kradblatt/editions
200

Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.
https://online.kradblatt.de/de/profiles/fa9830ee2805-kradblatt/editions
200

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
https://online.kradblatt.de/de/profiles/fa9830ee2805-kradblatt/editions
200

Warning: Https connections (Standard Port 443) found without support of the http/2 protocol via ALPN. Http/2 is the new Http-Version (old: http 1.1) with some important new features. Update your server software so http/2 is available. Only one TCP-connection per Server (that's a performance boost), Header-Compression and Server Pushs are available. Domain Sharding and Inline-CSS/Javascript shouldn't used with http/2.
AGood: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 4 external CSS / JavaScript files found
Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 0 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 2 with Cache-Control max-age too short (minimum 7 days), 2 with Cache-Control long enough, 4 complete.

Browsers should cache and re-use these files. 12 image files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 12 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: All img-elements have a valid alt-attribute.: 12 img-elements found.
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

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
