Verify any website SSL certificate: validity, issuer, expiry date, SAN domains and chain details.
How to use this tool
- Enter your domain. Type the domain you want to test, for example qwhosting.com.
- Run the check. We open a live TLS connection to port 443 and read the presented certificate.
- Review expiry. Check days remaining and set a renewal reminder before it reaches zero.
- Fix issues. If the certificate is missing or expired, install a free SSL from your QW HOSTING cPanel.
Free SSL certificate checker
An SSL/TLS certificate encrypts the traffic between your visitors and your server. If it expires, is misconfigured or does not cover the exact hostname, every browser shows a full-page security warning and your traffic collapses. This free QW HOSTING SSL checker reads the live certificate directly from your server so you always know the real state of your HTTPS.
Common SSL problems and fixes
- Expired certificate — enable AutoSSL in cPanel so renewal happens automatically.
- Name mismatch — the certificate must include both example.com and www.example.com.
- Incomplete chain — install the CA intermediate bundle alongside your certificate.
- Mixed content — update internal http:// links and assets to https://.
Secure your website with QW HOSTING SSL hosting — free auto-renewing SSL is included on every shared cPanel, WordPress and business hosting plan.
Frequently asked questions
What does this SSL checker do?
It connects to your domain over HTTPS on port 443 and reads the live certificate: issuer, validity dates, days remaining, covered domains and signature algorithm.
How do I know my SSL is valid?
A valid certificate is issued by a trusted CA, has not expired, and lists your exact domain (or a matching wildcard) in the Common Name or SAN list.
Why does my SSL show as expired?
Certificates are issued for a fixed period — usually 90 days for Let's Encrypt. Auto-renewal must be enabled, which QW HOSTING configures automatically on every cPanel account.
Does SSL affect SEO?
Yes. HTTPS is a confirmed Google ranking signal, and browsers show a "Not secure" warning on HTTP pages which hurts conversions.
Is free SSL good enough?
For most websites yes. QW HOSTING includes free auto-renewing SSL on every hosting plan, with premium OV/EV certificates available for eCommerce and corporate sites.
