|
| 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.

| 3. DNS- and NameServer - Checks |
| A | Info:: 7 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
|
| A | Info:: 7 Queries complete, 7 with IPv6, 0 with IPv4.
|
| A | Good: All DNS Queries done via IPv6.
|
| Ok (4 - 8):: An average of 3.5 queries per domain name server required to find all ip addresses of all name servers.
|
| A | Info:: 2 different Name Servers found: free5.googiehost.com, free6.googiehost.com, 2 Name Servers included in Delegation: free5.googiehost.com, free6.googiehost.com, 2 Name Servers included in 1 Zone definitions: free5.googiehost.com, free6.googiehost.com, 1 Name Servers listed in SOA.Primary: free5.googiehost.com.
|

|
| A | Good: SOA.Primary Name Server included in the delegation set.: free5.googiehost.com.
|
| A | Good: All Name Server Domain Names have a Public Suffix.
|

|
| A | Good: All Name Server ip addresses are public.
|
| A | Info: Ipv4-Subnet-list: 2 Name Servers, 1 different subnets (first Byte): 198., 1 different subnets (first two Bytes): 198.45., 1 different subnets (first three Bytes): 198.45.114.
|
| X | Fatal: All Name Server IPv4 addresses from the same subnet. Check https://www.iana.org/help/nameserver-requirements to learn some basics about name server configurations. If you manage these name servers, fix it. If it's your provider, change your provider.:
|
| A | Good: Nameserver supports TCP connections: 2 good Nameserver
|
| A | Good: Nameserver supports Echo Capitalization: 2 good Nameserver
|
| A | Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 2 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).
|
| https://danproject.c1.is/ 198.45.114.194
|
| Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.

|
| https://danproject.c1.is/ 198.45.114.194
|
| 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.

|
| A | Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
|
| https://danproject.c1.is/ 198.45.114.194
|
| Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage. Use "async" if the js file has only functions (so nothing is executed after parsing the file) or is independend. Use "defer" if the order of the scripts is important. All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 1 script elements without defer/async.

|
| A | Good: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 6 external CSS / JavaScript files found
|
| A | Good: 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. 6 external CSS / JavaScript files with long Cache-Control max-age found
|
| A | Good: All images are sent with a long Cache-Control header (minimum 7 days). So the browser can reuse these files, no download is required. 14 image files with long Cache-Control max-age found
|
| A | Good: All checked attribute values are enclosed in quotation marks (" or ').
|
| A | Good: All img-elements have a valid alt-attribute.: 14 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
