SSL certificate expiry explained
Understand SSL/TLS certificate expiration, how to check certificate dates, and why expired certs break HTTPS.
What happens when SSL expires
Browsers show security warnings and may block access entirely. APIs fail, SEO rankings drop, and users lose trust. Most certificates are valid for 90 days (Let's Encrypt) or up to 13 months (commercial CAs).
How Qikot checks SSL
We query Certificate Transparency logs via crt.sh to find the latest certificate issued for your domain. No agent install, no port scanning — just enter your domain and get days-until-expiry instantly.
When to renew
Renew at least 14 days before expiry. Automate renewal with your hosting provider or ACME clients. Monitor production and staging domains separately.
