| Warning: Only one ip address found: www.dies-und-jenes.de 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: dies-und-jenes.de has no ipv6 address.

| B | https://dies-und-jenes.de/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
|
| Missing HSTS-Header
|
| C | Error - no preferred version www or non-www. Select one version as preferred version, then add a redirect https + not-preferred version to https + preferred version. Perhaps in your port 443 vHost something like "RewriteEngine on" + "RewriteCond %{SERVER_NAME} = example.com" + "ReWriteRule ^ https://www.example.com%{REQUEST_URI} [END,QSA,R=permanent]" (three rows, without the "). That should create a redirect https + example.com ⇒ https + www.example.com. Or switch both values to use the non-www version as your preferred version.
|
| C | Error - 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.
|
| E | http://www.dies-und-jenes.de/ 49.13.224.238
| https://dies-und-jenes.de/
| 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.

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

| 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: object-src with a scheme definition found. That's too global, don't use such a definition. Use a list of urls instead if you really want to use object / embed / applet.

| 3. DNS- and NameServer - Checks |
| A | Info:: 52 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 4 Name Servers.

|
| A | Good: Only one SOA.Primary Name Server found.: ns1052.ui-dns.biz.
|
| A | Good: SOA.Primary Name Server included in the delegation set.: ns1052.ui-dns.biz.
|
| 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: ns1052.ui-dns.biz, ns1062.ui-dns.com, ns1088.ui-dns.de, ns1112.ui-dns.org
|
| A | Good: All Name Server Domain Names have a Public Suffix.
|
| A | Good: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
|
| A | Good: All Name Server ip addresses are public.
|
| A | Good: Minimal 2 different name servers (public suffix and public ip address) found: 4 different Name Servers found
|
| A | Good: All name servers have ipv4- and ipv6-addresses.: 4 different Name Servers found
|
| A | Good: Name servers with different Top Level Domains / Public Suffix List entries found: 4 Name Servers, 4 Top Level Domains: de, org, com, biz
|
| A | Good: Name Servers with different domain names found.: 4 different Domains found
|
| A | Good: Name servers with different Country locations found: 4 Name Servers, 2 Countries: DE, US
|
| A | Info: Ipv4-Subnet-list: 4 Name Servers, 1 different subnets (first Byte): 217., 1 different subnets (first two Bytes): 217.160., 4 different subnets (first three Bytes): 217.160.80., 217.160.81., 217.160.82., 217.160.83.

|
| A | Good: Name Server IPv6 addresses from different subnets found.
|
| A | Good: Nameserver supports TCP connections: 8 good Nameserver
|
| A | Good: Nameserver supports Echo Capitalization: 8 good Nameserver
|
| A | Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 8 good Nameserver

|
| A | Good: 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 |
| 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: No https + http status 200 with inline CSS / JavaScript found
|
| 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 | Good: 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.
|
| Warning: CSS / JavaScript found without Compression. Compress these ressources, gzip, deflate, br are checked. 6 external CSS / JavaScript files without Compression found - 2 with Compression, 8 complete
|
| Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 6 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), 6 with Cache-Control long enough, 12 complete.
|
| A | Good: All checked attribute values are enclosed in quotation marks (" or ').
|
| A | Good: All img-elements have a valid alt-attribute.: 3 img-elements found.
|
| 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
