Know what you have
Understand your certificate's issuer, validity and expiry. An expired certificate takes the site down with a full-page warning.
An expired certificate doesn't just look bad — browsers block the whole site with a scary full-page warning until you renew.
Automate renewal
Free Let's Encrypt certificates auto-renew — if configured. Confirm renewal is working and monitor the expiry date so it never lapses.
Monitor it
Set an expiry alert (or use a host/care plan that monitors for you). (Our free audit now reports your certificate's issuer and days-to-expiry.)
Key takeaway
Know your certificate, automate its renewal, and monitor the expiry so it never catches you out.
