This checks that every version of your site — http://, https://, with or without www — actually serves over HTTPS, and that plain HTTP requests get redirected rather than served directly.
HTTP pages are marked "Not Secure" in Chrome. Google requires HTTPS for Core Web Vitals measurement and uses it as a ranking signal. Any page serving over HTTP is losing trust and rankings.
Every variant (http, https, www, non-www) redirects to a single https:// URL with a valid, trusted certificate.
Fix it, then re-scan — the check confirms itself. No manual checkbox, the scan is the truth.
