DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "aqc03q7t6gre78sh5ih0thi35k8kv5dl" between the hashed NSEC3-owner "aqc03q7t6gre78sh5ih0thi35k8kv5dl" and the hashed NextOwner "aqc0aq0eivu64mc1a0pvusu98jkk2j1u". So the parent zone confirmes the not-existence of a DS RR.

AGood - only one version with Http-Status 200
AGood: one preferred version: non-www is preferred
AGood: No cookie sent via http.
AGood: every https has a Strict Transport Security Header
AGood: HSTS max-age is long enough, 31536000 seconds = 365 days
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.
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)

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.

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.

2. Header-Checks (Cross-Origin-* headers are alpha - started 2024-06-05)

A4bis.nl
Content-Security-Policy
Ok: Header without syntax errors found: default-src blob: https: data: 'unsafe-eval' 'unsafe-inline'; frame-ancestors 'self';
F

Bad: default-src with "*" or a scheme found. That allows too much, don't use such a definition.
F

Bad: default-src with 'unsafe-inline' or 'unsave-eval'. That's dangerous, don't use it.
E

Bad: No form-action directive found. Use one to limit the form - action - destinations. form-action is a navigation-directive, so default-src isn't used.
A

Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
E

Bad: No base-uri directive found. Use one to limit the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
E

Critical: No object-src defined, the default-src used as fallback allows too much. object / embed / applet shouldn't be able to load these resources.
E

Critical: No script-src defined, the default-src used as fallback allows too much. script-src should always restricted.
F

Dangerous: No script-src defined, but the default-src as fallback allows the data: schema. That allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.
F

Dangerous: No frame-src defined, but the default-src used as fallback allows the data: schema. That allows hidden code injection. Insert <iframe src="data:text/html;charset=utf-8;base64,PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PHA+YmVmb3JlPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPmFsZXJ0KCdYU1MnKTwvc2NyaXB0PjxwPmFmdGVyPC9ib2R5PjwvaHRtbD4="></iframe> in your page and see what happens.
A
X-Content-Type-Options
Ok: Header without syntax errors found: nosniff
A
Referrer-Policy
Ok: Header without syntax errors found: strict-origin-when-cross-origin
A
X-Frame-Options
Ok: Header without syntax errors found: SAMEORIGIN
B

Info: Header is deprecated. May not longer work in modern browsers. SAMEORIGIN. Better solution: Use a Content-Security-Policy Header with a frame-ancestors directive. DENY - use 'none', SAMEORIGIN - use 'self'. If you want to allow some domains to frame your page, add these urls.
F4bis.nl
Permissions-Policy
Critical: Missing Header:

3. DNS- and NameServer - Checks

AInfo:: 13 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 4 Name Servers.
AInfo:: 13 Queries complete, 13 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
Ok (4 - 8):: An average of 3.3 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 4 different Name Servers found: ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com, ns-cloud-e4.googledomains.com, 4 Name Servers included in Delegation: ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com, ns-cloud-e4.googledomains.com, 4 Name Servers included in 1 Zone definitions: ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com, ns-cloud-e4.googledomains.com, 1 Name Servers listed in SOA.Primary: ns-cloud-e1.googledomains.com.
AGood: Only one SOA.Primary Name Server found.: ns-cloud-e1.googledomains.com.
AGood: SOA.Primary Name Server included in the delegation set.: ns-cloud-e1.googledomains.com.
AGood: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com, ns-cloud-e4.googledomains.com
AGood: All Name Server Domain Names have a Public Suffix.
AGood: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
AGood: All Name Server ip addresses are public.
AGood: Minimal 2 different name servers (public suffix and public ip address) found: 4 different Name Servers found
AGood: All name servers have ipv4- and ipv6-addresses.: 4 different Name Servers found
Warning: All Name Servers have the same Top Level Domain / Public Suffix. If there is a problem with that Top Level Domain, your domain may be affected. Better: Use Name Servers with different top level domains.: 4 Name Servers, 1 Top Level Domain: com
Warning: All Name Servers have the same domain name. If there is a problem with that domain name (or with the name servers of that domain name), your domain may be affected. Better: Use Name Servers with different domain names / different top level domains.: Only one domain name used: googledomains.com
Warning: All Name Servers from the same Country / IP location.: 4 Name Servers, 1 Countries: US
AInfo: Ipv4-Subnet-list: 4 Name Servers, 1 different subnets (first Byte): 216., 1 different subnets (first two Bytes): 216.239., 4 different subnets (first three Bytes): 216.239.32., 216.239.34., 216.239.36., 216.239.38.

AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 8 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 8 good Nameserver
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 supports GZip.
https://4bis.nl/nl/
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.

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://4bis.nl/nl/domain-registered?domain=[2001:1af8:4900:a031:3:0:4b10:11]
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.
AGood: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
AGood: All script Elements (type text/javascript) and src-Attribute have a defer / async - Attribute. So loading and executing these JavaScripts doesn't block parsing and rendering the Html-Output.
AGood: All CSS / JavaScript files are sent with GZip. That reduces the content of the files. 5 external CSS / JavaScript files found
AGood: All images with internal compression not sent via GZip. Images (.png, .jpg) are already compressed, so an additional GZip isn't helpful. 1 images (type image/png, image/jpg) found without additional GZip. Not required because these images are already compressed
Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 20 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 5 with Cache-Control long enough, 25 complete.
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 28 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), 6 with Cache-Control long enough, 34 complete.
AGood: Some checked attribute values are enclosed in quotation marks (" or ').: 569 Html-Elements checked, 46 without problems.
IWrong: Attribute values found, not enclosed in quotation marks (" or ').: 523 Html-Elements with attributes and missing enclosed quotation marks found. 568 wrong attributes.
AGood: All img-elements have a valid alt-attribute.: 34 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
