Use this SSL certificate checker to check HTTPS availability, SSL expiry, certificate issuer, validity dates, domain coverage, and basic SSL health.

What Is an SSL Certificate?
An SSL certificate is a digital certificate that helps secure communication between a browser and a website. When SSL is installed correctly, visitors can open your website using HTTPS and browsers show a secure connection instead of a warning.
Why SSL Matters for Websites
SSL helps protect login forms, checkout pages, contact forms, customer data, admin panels, and online transactions. It also improves visitor trust because modern browsers warn users when a website is not secure.
Common SSL Problems
- SSL certificate expired
- SSL installed for the wrong domain
- www and non-www versions not covered
- Missing intermediate certificate chain
- Mixed content errors after moving to HTTPS
- DNS not pointing to the correct hosting server
- Website still redirecting to HTTP instead of HTTPS
How to Fix SSL Issues
To fix SSL issues, confirm your domain points to the correct hosting account, install or renew the SSL certificate, force HTTPS redirection, update WordPress site URLs if needed, fix mixed content, and check that both www and non-www versions are covered by the certificate.
