DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "g3t2iopvqm41vlsp395qck8hploajce0" between the hashed NSEC3-owner "g3sivbk2qusde859e6u156jpcsjd5b64" and the hashed NextOwner "g3vhui9fcni5vlp58mssjjdkpd55tquu". 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 "25epi9j7p37c9ckovkj018n051f6qpv7" as Owner. That's the Hash of "mmrmedia.xs4all.nl" with the NextHashedOwnerName "25jntlj2a711ajrr6fj4h5gv39vpleih". So that domain name is the Closest Encloser of "www.mmrmedia.xs4all.nl". Opt-Out: False.

The ClosestEncloser says, that "*.mmrmedia.xs4all.nl" with the Hash "04rgskrao7ivlqs09tpqu72i8g0nfva8" 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 "04r5bdghieg9bkk32bga523ohoonur67" and the Next Owner "04vbbr5spnmvsk1eq8ru13e4ckhufulv", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion. Opt-Out: False.

1. General Results, most used to calculate the result

Aname "mmrmedia.xs4all.nl" is subdomain, public suffix is ".nl", top-level-domain is ".nl", top-level-domain-type is "country-code", Country is Netherlands (the), tld-manager is "SIDN (Stichting Internet Domeinregistratie Nederland)", num .nl-domains preloaded: 3760 (complete: 168171)
Agood: All ip addresses are public addresses
Warning: Only one ip address found: mmrmedia.xs4all.nl has only one ip address.
Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: mmrmedia.xs4all.nl has no ipv6 address.
Agood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
AGood: No cookie sent via http.
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: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):1 complete Content-Type - header (3 urls)
http://mmrmedia.xs4all.nl/ 80.100.158.243


Url with incomplete Content-Type - header - missing charset
http://mmrmedia.xs4all.nl:443/ 80.100.158.243


Url with incomplete Content-Type - header - missing charset
CError - more then one version with Http-Status 200. After all redirects, all users (and search engines) should see the same https url: Non-www or www, but not both with http status 200.
Hfatal error: No https - result with http-status 200, no encryption
HFatal error: http result with http-status 200, no encryption. Add a redirect http ⇒ https, so every connection is secure. 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.
Qhttp://mmrmedia.xs4all.nl:443/ 80.100.158.243
200

Misconfiguration: http sent over port 443. Wrong port forwarding port 443 to port 80 or wrong vHost definition. If you use a virtual Host <VirtualHost ip-address:443>, try <VirtualHost *:443>.
Info: Checking the ip addresses of that domain name not exact one certificate found. So it's impossible to check if that domain requires Server Name Indication (SNI).: Domain mmrmedia.xs4all.nl, 1 ip addresses.

2. DNS- and NameServer - Checks

AInfo:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.

3. 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.
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
