1. General Results, most used to calculate the result

Aname "" is ipv4 address, public suffix is not defined
AGood: All ip addresses are public addresses
AGood: No cookie sent via http.
AGood: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):0 complete Content-Type - header (2 urls)

Url with incomplete Content-Type - header - missing charset

Url with incomplete Content-Type - header - missing charset
CError - no version with Http-Status 200
HFatal error: No https - result with http-status 200, no encryption

Misconfiguration - main pages should never send http status 400 - 499
BNo _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.

2. Header-Checks (Cross-Origin-* headers are alpha - started 2024-06-05)


No https result with http status 2** or 4** (standard-check) found, no header checked.

3. DNS- and NameServer - Checks

4. Content- and Performance-critical Checks

AGood: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use to ask.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AInfo: No img element found, no alt attribute checked
ADuration: 28353 milliseconds, 28.353 seconds

8. Connections

No connection informations found. Perhaps only http - connections.

9. Certificates

No certificate informations found. Perhaps only http - connections.

10. Last Certificates - Certificate Transparency Log Check

1. Source CertSpotter - active certificates (one check per day)

No CertSpotter - CT-Log entries found

2. Source - old and new certificates, sometimes very slow - only certificates with "not after" > of the last months are listed

No CRT - CT-Log entries found

11. Html-Content - Entries

No Html-Content entries found. Only checked if https + status 200/401/403/404

12. Nameserver - IP-Adresses

Required Root-climbing DNS-Queries to find ip addresses of all Name Servers:

No NameServer - IP address - Informations found

13. CAA - Entries

No CAA entries found

14. TXT - Entries

No TXT entries found

15. DomainService - Entries

No DomainServiceEntries entries found

16. Cipher Suites

No results

17. Portchecks
