| Error - Certificate isn't trusted, RemoteCertificateNameMismatch
|
| 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 global.ketchcdn.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 different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain global.ketchcdn.com, 2 ip addresses.

| A | global.ketchcdn.com 151.101.5.91
| Content-Security-Policy
| Ok: Header without syntax errors found: default-src 'self'
|
| A |
|
| Good: default-src directive only with 'none' or 'self', additional sources are blocked.
|
| A |
|
| Good: default-src without 'unsafe-inline' or 'unsave-eval'.
|
| E |
|
| Bad: No form-action directive found. Use one to limit the form - action - destinations. form-action is a navigation-directive, so default-src isn't used.
|
| E |
|
| Bad: No frame-ancestors directive found. Use one to limit the pages allowed to use this page in frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
|
| E |
|
| Bad: No base-uri directive found. Use one to limit the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
|
| A |

|
| A |
|
| Good: No script-src found, but the default-src used as fallback is defined and restricted.
|
| A |
|
| Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks hidden code injection.

|
| 4. Content- and Performance-critical Checks |
| A | Good: 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 https://community.letsencrypt.org/ to ask.
|
| A | Good: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
|
| A | Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
|
| 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
