|
| C | Error - no preferred version www or non-www. Select one version as preferred version, then add a redirect https + not-preferred version to https + preferred version.

That should create a redirect https + example.com ⇒ https + www.example.com. Or switch both values to use the non-www version as your preferred version.
|
| C | Error - more then one version with Http-Status 200. After all redirects, all users (and search engines) should see the same https url: Non-www or www, but not both with http status 200.

|
| 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 different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain spllr.dev, 2 ip addresses.

|
| 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 |
| https://spllr.dev/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
|
| Warning: Not existing ACME-file, but Server sends 200, not 404 or redirect. May be a problem creating a Letsencrypt certificate. Checking /.well-known/acme-challenge/random-filename - a http status 404 - Not Found - is expected. If your server sends content and a http status 200, the validation file (87 bytes, token, dot and the hash of the public part of the account key) may be invisible, so Letsencrypt can't validate your domain. If it is an application that sends this content, perhaps create an exception, so /.well-known/acme-challenge sends raw files. Or create a redirect to another domain and / or port 443, but your Letsencrypt client must support such a solution. Certbot: Use webroot as authenticator - https://certbot.eff.org/docs/using.html Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

| 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
