0 DS RR in the parent zone found






DS-Query in the parent zone has a valid NSEC RR as result with the domain name between the NSEC-Owner "app.ctman.net" and the NextOwner "\000.app.ctman.net". So the parent zone confirmes the non-existence of a DS RR.

1. General Results, most used to calculate the result

Aname "app.ctman.net" is subdomain, public suffix is ".net", top-level-domain is ".net", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .net-domains preloaded: 10583 (complete: 276475)
AGood: All ip addresses are public addresses
AGood: Minimal 2 ip addresses per domain name found: app.ctman.net has 4 different ip addresses (authoritative).
AGood: Ipv4 and Ipv6 addresses per domain name found: app.ctman.net has 2 ipv4, 2 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)

AGood: More then one ip address per domain name found, checking all ip addresses the same http status and the same certificate found: Domain app.ctman.net, 4 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 app.ctman.net, 4 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.app.ctman.net

Ok: Header without syntax errors found: default-src 'none'; script-src 'sha256-kVPvHotP68a1EPGB+xSP2UYKrBZPwTR9U1bsOD96Tlw='; style-src 'sha256-yWuyd3ZveS0bS9EWqy9gdUBAuWedJOdCsv08HZlrsn8='; img-src 'self' data:; connect-src 'self'; base-uri 'none'; form-action 'none'; frame-ancestors 'none'
A

Good: default-src directive only with 'none' or 'self', additional sources are blocked.
A

Good: default-src without 'unsafe-inline' or 'unsave-eval'.
A

Good: form-action directive found. That reduces the risk sending data to unwanted domains. 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: No object-src found, but the default-src used as fallback is defined and restricted.
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.
A

Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks 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

Good: form-action directive found. That reduces the risk sending data to unwanted domains. form-action is a navigation-directive, so default-src isn't used.

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: cloudflare.com
AGood: Name servers with different Country locations found: 2 Name Servers, 4 Countries: CA, CR, GB, US
AInfo: Ipv4-Subnet-list: 6 Name Servers, 4 different subnets (first Byte): 108., 162., 172., 173., 4 different subnets (first two Bytes): 108.162., 162.159., 172.64., 173.245., 6 different subnets (first three Bytes): 108.162.193., 108.162.194., 162.159.38., 172.64.33., 172.64.34., 173.245.59.

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: Every https connection via port 443 supports the http/2 protocol via ALPN.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
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
