AGood: 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.

3. Content- and Performance-critical Checks

401

Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 401 / 403 Not Allowed / Forbidden. A http status 404 - Not Found - is expected. Creating a Letsencrypt certificate via http-01 challenge may not work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
https://transitnotifier.mac2796.duckdns.org/ 212.75.107.21
200

Warning: https result with status 200 and size greater then 1024 Bytes without GZip found. Add GZip support so the html content is compressed.
AGood: No https + http status 200 with inline CSS / JavaScript found
AGood: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
https://transitnotifier.mac2796.duckdns.org/ 212.75.107.21
200

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.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AInfo: No img element found, no alt attribute checked
AGood: 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
