| A | name "spotify.com" is domain, public suffix is ".com", top-level-domain is ".com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .com-domains preloaded: 108094 (complete: 276475)
|
| A | Good: All ip addresses are public addresses
|
| A | Good: Minimal 2 ip addresses per domain name found: spotify.com has 3 different ip addresses (authoritative).
|
| A | Good: Minimal 2 ip addresses per domain name found: www.spotify.com has 2 different ip addresses (authoritative).

| A | http://www.spotify.com/ 35.186.224.24
| https://www.spotify.com/
| Correct redirect http - https with the same domain name
|
| A | http://www.spotify.com/ 2600:1901:1:7c5::
| https://www.spotify.com/
| Correct redirect http - https with the same domain name
|
| E | http://spotify.com/ 35.186.224.24
| https://www.spotify.com/
| 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.

| Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain spotify.com, 2 ip addresses.

|
| F |
|
| 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.
|
| 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.
|
| F |
|
| Critical: No object-src and no default-src as fallback defined. So object / embed / applet can load every resource. That's fatal.
|
| F |
|
| Critical: script-src with 'unsafe-inline' or 'unsafe-eval' and without a nonce found. That's dangerous, don't use it. If you really need one of these unsafe directives, add a nonce.
|
| F |
|
| Critical: script-src with * or a scheme found. Never allow wildcard - sources.
|
| 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.

|
| Ok (4 - 8):: An average of 3.4 queries per domain name server required to find all ip addresses of all name servers.
|
| A | Info:: 5 different Name Servers found: dns1.p07.nsone.net, ns-cloud-a1.googledomains.com, ns-cloud-a2.googledomains.com, ns-cloud-a3.googledomains.com, ns-cloud-a4.googledomains.com, 5 Name Servers included in Delegation: dns1.p07.nsone.net, ns-cloud-a1.googledomains.com, ns-cloud-a2.googledomains.com, ns-cloud-a3.googledomains.com, ns-cloud-a4.googledomains.com, 5 Name Servers included in 1 Zone definitions: dns1.p07.nsone.net, ns-cloud-a1.googledomains.com, ns-cloud-a2.googledomains.com, ns-cloud-a3.googledomains.com, ns-cloud-a4.googledomains.com, 2 Name Servers listed in SOA.Primary: dns1.p07.nsone.net, ns-cloud-a1.googledomains.com.
|
| Error: Different SOA.Primary Name Servers found, different SOA Definitions.: dns1.p07.nsone.net,ns-cloud-a1.googledomains.com.
|
| A | Good: SOA.Primary Name Server included in the delegation set.: dns1.p07.nsone.net,ns-cloud-a1.googledomains.com.
|
| A | Good: 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: dns1.p07.nsone.net, ns-cloud-a1.googledomains.com, ns-cloud-a2.googledomains.com, ns-cloud-a3.googledomains.com, ns-cloud-a4.googledomains.com

|
| A | Good: Name Server IPv4-addresses from different subnet found:
|
| A | Info: IPv6-Subnet-list: 5 Name Servers with IPv6, 2 different subnets (first block): 2001:, 2620:, 2 different subnets (first two blocks): 2001:4860:, 2620:004d:, 2 different subnets (first three blocks): 2001:4860:4802:, 2620:004d:4000:, 5 different subnets (first four blocks): 2001:4860:4802:0032:, 2001:4860:4802:0034:, 2001:4860:4802:0036:, 2001:4860:4802:0038:, 2620:004d:4000:6259:
|
| A | Good: Name Server IPv6 addresses from different subnets found.

|
| X | Fatal error: Nameservers with different SOA Serial Numbers
|
| 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 |
| A | Good: 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.
|
| A | Good: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
|
| A | Good: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
|
| A | Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
|
| A | Info: No img element found, no alt attribute checked
|
| 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
