Info: Problems with 3.048.289 Letsencrypt certificates (378.325 accounts). They must be revoked (revocation starts 2020-03-04 20:00 UTC) - see Revoking certain certificates on March 4. Update 2020-03-07: Good news: Mass-revocation is canceled.

This tool: A check (SerialNumber) is added. Letsencrypt has published a list of critical SerialNumbers, this list is checked. See the part "9. Certificates". If there is a warning, renew that certificate and replace the current certificate.

1. General Results, most used to calculate the result

Aname "luismaier.de" is domain, public suffix is "de", top-level-domain-type is "country-code", Country is Germany, tld-manager is "DENIC eG"
Agood: All ip addresses are public addresses
Agood: No asked Authoritative Name Server had a timeout
Agood: every https has a Strict Transport Security Header
AHSTS max-age is short - minimum 31536000 = 365 days required, 15768000 seconds = 182 days found, but not a problem because domain has an old preload-entry (Google-Policy: bulk-18-weeks)
Agood: HSTS has includeSubdomains - directive
Agood: HSTS has preload directive
AExcellent: Domain is in the Google-Preload-List
AExcellent: Domain is in the Mozilla/Firefox-Preload-List
AHSTS-Preload-Status: Preloaded. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)

Ehttp://luismaier.de/ 83.169.2.183
301
https://www.luismaier.dehttps://luismaier.de//
Wrong redirect one domain http to other domain https. First redirect to https without new dns query, so the server can send the HSTS header. That's fundamental using HSTS (Http Strict Transport Security). First step: Add correct redirects http ⇒ https. Perhaps in your port 80 vHost something like "RewriteEngine on" + "RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]" (two rows, without the "). Don't add this in your port 443 vHost, that would create a loop. Then recheck your domain, should be Grade C. There is the rule to select one https version as preferred version.
Hfatal error: No https - result with http-status 200, no encryption

Fatal: Check of /.well-known/acme-challenge/random-filename redirects to not-existing domain. Creating a Letsencrypt certificate via http-01 challenge can't work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
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
