SSL Checker
NewVerify a domain's DNS resolution status and connectivity to confirm the site is live and reachable — a key prerequisite for valid SSL/HTTPS configuration. A domain that resolves correctly to a server is the foundation for proper SSL certificate installation. Use this tool to quickly check whether a domain is pointing to a live server before diagnosing SSL or HTTPS issues. Useful for webmasters confirming new domains are propagated, developers verifying staging environments are accessible, and anyone troubleshooting HTTPS errors.
Enter a domain to check its DNS resolution and SSL status.

Frequently Asked Questions
Why can't it show the full SSL certificate?
Browsers cannot directly access raw TLS/SSL certificate details from external domains due to security restrictions. Full certificate inspection (expiry date, issuer, SANs) requires a server-side check or browser developer tools.
What does "DNS resolved" mean for SSL?
If DNS resolves successfully, the domain points to a live server — which is the prerequisite for SSL. If DNS does not resolve, no SSL certificate will work because browsers cannot reach the server at all.
What should I check if my SSL certificate shows as invalid in browsers?
Common causes include: expired certificate, certificate issued for a different domain, missing intermediate certificates, or HTTP redirecting incorrectly. Use your browser's lock icon > Certificate details for full inspection.
How do I check an SSL certificate's expiry date?
In Chrome, click the padlock icon in the address bar > Connection is secure > Certificate is valid. This shows the full certificate chain, issuer, and expiry date directly from your browser.
