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 cp2.cloudflare.com, 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 cp2.cloudflare.com, 2 ip addresses, 1 different http results.
B	No _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.cp2.cloudflare.com

	4. Content- and Performance-critical Checks
	http://cp2.cloudflare.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 162.159.194.60	403	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.
	http://cp2.cloudflare.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 2606:4700:101::a29f:c23c	403	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.
A	Good: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 2 external CSS / JavaScript files 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
