	DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "h8r84lf7f5qaph8eh2lg44jeitrbimom" between the hashed NSEC3-owner "dv47ujrh003ok66u71sr275qb3nq1j38" and the hashed NextOwner "heri84sfsvpp592q7iosafrtmaln1bpf". So the parent zone confirmes the not-existence of a DS RR.

	DS-Query in the parent zone sends valid NSEC3 RR with the Hash "2k8h2av5146b1lt66p077g463qkksr5j" as Owner. That's the Hash of "pix.kadercon.nl" with the NextHashedOwnerName "4087qmk1kin2mjhe48j6t2g844fve9t3". So that domain name is the Closest Encloser of "www.pix.kadercon.nl". Opt-Out: False.

	The ClosestEncloser says, that "*.pix.kadercon.nl" with the Hash "82s3m5ti2g7mia1f9p8ug87rvr00ob86" is a possible Wildcard of the DS Query Name. But the DS-Query in the parent zone sends a valid NSEC3 RR With the owner "8296a3ap2bikbnql93301ptdmhmtrou3" and the Next Owner "a70ldkkd3h9en3njeicuoukqs852bc00", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion. Opt-Out: False.

	4. Content- and Performance-critical Checks
	https://pix.kadercon.nl/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de	401		Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 401 / 403 Not Allowed / Forbidden. A http status 404 - Not Found - is expected. Creating a Letsencrypt certificate via http-01 challenge may not work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
	https://pix.kadercon.nl/admin/public/index.html	200		Warning: https result with status 200 and size greater then 1024 Bytes without Compression found. Add Compression support (gzip, deflate, br - these are checked) so the html content is compressed.
	https://pix.kadercon.nl/admin/public/index.html	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://pix.kadercon.nl/admin/public/index.html	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://pix.kadercon.nl/admin/public/index.html	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.
	Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 1 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, 1 complete.
A	Good: All checked attribute values are enclosed in quotation marks (" or ').
A	Good: All img-elements have a valid alt-attribute.: 1 img-elements found.
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
