Checks how many days until the SSL/TLS certificate expires and alerts if expiration is imminent.
This check examines your SSL/TLS certificate's expiration date and warns you when it's approaching expiry. Certificates expiring within 30 days trigger a warning; within 7 days triggers a critical alert. Expired certificates make your site inaccessible via HTTPS.
An expired SSL certificate causes browsers to show a full-page warning that effectively blocks all visitors from accessing your site. This is one of the most damaging technical issues possible — your site becomes completely inaccessible to most users.
An expired certificate immediately kills all website traffic. Browsers show scary security warnings that prevent users from proceeding. Search engines will also stop crawling HTTPS pages, causing rapid de-indexing of your content.
