| X | Fatal error: Nameserver doesn't support TCP connection: master.dns.ne.jp / 210.224.172.18: Timeout
|
| A | Good: More then one ip address per domain name found, checking all ip addresses the same http status and the same certificate found: Domain mail.0946.me, 2 ip addresses.
|
| 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 the same. So that domain doesn't require Server Name Indication (SNI), it's the primary certificate of that set of ip addresses.: Domain mail.0946.me, 2 ip addresses, 1 different http results.

|
| A | Good (1 - 3.0):: An average of 1.0 queries per domain name server required to find all ip addresses of all name servers.
|
| A | Info:: 3 different Name Servers found: master.dns.ne.jp, ns1.dns.ne.jp, ns2.dns.ne.jp, 2 Name Servers included in Delegation: ns1.dns.ne.jp, ns2.dns.ne.jp, 2 Name Servers included in 2 Zone definitions: ns1.dns.ne.jp, ns2.dns.ne.jp, 1 Name Servers listed in SOA.Primary: master.dns.ne.jp.

|
| 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: 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 %.

| Warning: Https connections (Standard Port 443) found without support of the http/2 protocol via ALPN. Http/2 is the new Http-Version (old: http 1.1) with some important new features. Update your server software so http/2 is available. Only one TCP-connection per Server (that's a performance boost), Header-Compression and Server Pushs are available. Domain Sharding and Inline-CSS/Javascript shouldn't used with http/2.

| A | Good: All checked attribute values are enclosed in quotation marks (" or ').
|
| 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
