| Fatal: More then one ip address per domain name found, but checking all ip addresses different http status found.: Domain snowfox.at, 2 ip addresses, 2 different http results.

|
| 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: ns1.domain.com, ns2.domain.com, 2 Name Servers included in Delegation: ns1.domain.com, ns2.domain.com, 2 Name Servers included in 1 Zone definitions: ns1.domain.com, ns2.domain.com, 1 Name Servers listed in SOA.Primary: ns1.domain.com.

|
| A | Good: SOA.Primary Name Server included in the delegation set.: ns1.domain.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: ns1.domain.com, ns2.domain.com

|
| Warning: No Name Server IPv6 address found. IPv6 is the future, so your name servers should be visible via IPv6.: 2 different Name Servers found
|
| Warning: All Name Servers have the same Top Level Domain / Public Suffix. If there is a problem with that Top Level Domain, your domain may be affected. Better: Use Name Servers with different top level domains.: 2 Name Servers, 1 Top Level Domain: com
|
| 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: domain.com
|

| 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.

| http://snowfox.at/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 90.152.144.7
|
| Fatal: Check of /.well-known/acme-challenge/random-filename has a timeout. Creating a Letsencrypt certificate via http-01 challenge can't work. You need a running webserver (http) and an open port 80. If it's a home server + ipv4, perhaps a correct port forwarding port 80 extern ⇒ working port intern is required. Port 80 / http can redirect to another domain port 80 or port 443, but not other ports. If it's a home server, perhaps your ISP blocks port 80. Then you may use the dns-01 challenge. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

|
| 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. 1 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. 1 external CSS / JavaScript files with long Cache-Control max-age found
|
| 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
