DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "qikl8qc1u6s50du950kgjihttn6v6ttn" between the hashed NSEC3-owner "qikkpln05226jc6vfd2ud5l2r1gncj4g" and the hashed NextOwner "qiklp0aq11tlkm45hn0m06h6qs1666vh". So the parent zone confirmes the not-existence of a DS RR.

1. General Results, most used to calculate the result

Aname "forum.riot-os.org" is subdomain, public suffix is ".org", top-level-domain is ".org", top-level-domain-type is "generic", tld-manager is "Public Interest Registry (PIR)", num .org-domains preloaded: 8524 (complete: 245733)
AGood: All ip addresses are public addresses
AGood: Minimal 2 ip addresses per domain name found: forum.riot-os.org has 2 different ip addresses (authoritative).
AGood: Ipv4 and Ipv6 addresses per domain name found: forum.riot-os.org has 1 ipv4, 1 ipv6 addresses
AGood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: non-www is preferred
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: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)

Missing HSTS-Header
AGood: More then one ip address per domain name found, checking all ip addresses the same http status and the same certificate found: Domain forum.riot-os.org, 2 ip addresses.
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 forum.riot-os.org, 2 ip addresses.
BNo _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.forum.riot-os.org

Bad: Missing default-src directive. A default-src directive is used if one of the specialized fetch directives (child-src, connect-src, font-src, frame-src, img-src, manifest-src, media-src, object-src, prefetch-src, script-src, style-src, worker-src) isn't defined. Missing default-src, all sources are allowed, that's bad. A default-src with 'none' or 'self' blocks that.
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.
A

Good: base-uri directive found. That limits 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.
A

Good: object-src only with 'none' or 'self' found, no scheme, no other urls. That blocks object / embed / applet - elements.
A

Good: script-src without 'unsafe-inline' and 'unsafe-eval' found. That's the recommended configuration.
A

Good: script-src without * and a scheme found.
A

Good: script-src without data: schema found. Why is this important? The data: schema allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.

3. DNS- and NameServer - Checks

AInfo:: 17 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 4 Name Servers.
AInfo:: 17 Queries complete, 17 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
Ok (4 - 8):: An average of 4.3 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 4 different Name Servers found: nsa4.schlundtech.de, nsb4.schlundtech.de, nsc4.schlundtech.de, nsd4.schlundtech.de, 4 Name Servers included in Delegation: nsa4.schlundtech.de, nsb4.schlundtech.de, nsc4.schlundtech.de, nsd4.schlundtech.de, 4 Name Servers included in 1 Zone definitions: nsa4.schlundtech.de, nsb4.schlundtech.de, nsc4.schlundtech.de, nsd4.schlundtech.de, 1 Name Servers listed in SOA.Primary: nsa4.schlundtech.de.
AGood: Only one SOA.Primary Name Server found.: nsa4.schlundtech.de.
AGood: SOA.Primary Name Server included in the delegation set.: nsa4.schlundtech.de.
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.
AInfo: Ipv4-Subnet-list: 4 Name Servers, 4 different subnets (first Byte): 217., 62., 74., 89., 4 different subnets (first two Bytes): 217.160., 62.116., 74.208., 89.146., 4 different subnets (first three Bytes): 217.160.113., 62.116.159., 74.208.254., 89.146.248.
AExcellent: Every Name Server IPv4-address starts with an unique Byte.
AInfo: IPv6-Subnet-list: 3 Name Servers with IPv6, 3 different subnets (first block): 2001:, 2607:, 2a01:, 3 different subnets (first two blocks): 2001:08d8:, 2607:f1c0:, 2a01:0130:, 3 different subnets (first three blocks): 2001:08d8:0580:, 2607:f1c0:1800:, 2a01:0130:2000:, 3 different subnets (first four blocks): 2001:08d8:0580:0401:, 2607:f1c0:1800:8091:, 2a01:0130:2000:0118:
AExcellent: Every Name Server IPv6-address starts with an unique Hex-block
AGood: Nameserver supports TCP connections: 14 good Nameserver
AGood: Nameserver supports Echo Capitalization: 14 good Nameserver
XFatal error: Nameserver doesn't support EDNS with max. 512 Byte Udp payload or sends more then 512 Bytes: nsa4.schlundtech.de

XFatal error: Nameserver doesn't support EDNS with max. 512 Byte Udp payload or sends more then 512 Bytes: nsd4.schlundtech.de
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 14 good Nameserver
Nameserver doesn't pass all EDNS-Checks: nsa4.schlundtech.de: OP100: no result. FLAGS: no result. V1: no result. V1OP100: no result. V1FLAGS: no result. DNSSEC: no result. V1DNSSEC: no result. NSID: no result. COOKIE: no result. CLIENTSUBNET: no result.
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).
AGood: No https + http status 200 with inline CSS / JavaScript found
https://forum.riot-os.org/ 65.108.193.50
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://forum.riot-os.org/ 2a01:4f9:1a:9508::1
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.
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 compressed (gzip, deflate, br checked). That reduces the content of the files. 58 external CSS / JavaScript files found
AGood: All images with internal compression not compressed. Some Images (.png, .jpg, .jpeg, .webp, .gif) are already compressed, so an additional compression isn't helpful. 1 images (type image/png, image/jpg) found without additional GZip. Not required because these images are already compressed
AGood: All CSS / JavaScript files are sent with a long Cache-Control header (minimum 7 days). So the browser can re-use these files, no download is required. 58 external CSS / JavaScript files with long Cache-Control max-age found
AGood: All images are sent with a long Cache-Control header (minimum 7 days). So the browser can reuse these files, no download is required. 1 image files with long Cache-Control max-age found
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: All img-elements have a valid alt-attribute.: 1 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
