HTTPS endpoint is not accessible
The site could not be reached over HTTPS or returned an error.
Why it matters: HTTPS encrypts traffic and protects user data.
HTTP port 80 is not responding, so there is no HTTP listener to redirect. Modern browsers upgrade to HTTPS automatically.
Note: Port 80 may be firewalled or intentionally closed. Opening it with a 301 to HTTPS ensures visitors who type http:// are redirected rather than getting a connection error.
| Valid | No |
Why it matters: A valid, non-expired certificate ensures encryption is trusted by browsers.
To improve your grade
Requires 4 of 6 headers and Content-Security-Policy (CSP).
To improve your grade
No HTTPS record. Browsers discover protocols via connection — an HTTPS record speeds this up. Learn more →
No CAA records. Any CA can issue certificates. Consider adding CAA to restrict issuance.
When you visit the site over HTTP, the server may send you through one or more redirects until you land on the final HTTPS URL. Shorter chains are faster and better for SEO.
