Renewal and expiration

​​ Renew custom certificates

Since Cloudflare cannot renew uploaded certificates, you should ensure that you replace an expiring custom certificate before it expires, otherwise your visitors may not be able to connect.

Cloudflare automatically sends email notifications 30 and 14 days before your custom certificate expires. The email is sent to users who have the SSL/TLS, Administrator, or Super Administrator roles.

​​ Expired certificates

If a valid replacement is already available, Cloudflare will remove expiring custom certificates in the 24 hours before expiration. If no valid replacement is available, Cloudflare will remove the expiring custom certificate 30 minutes before it expires.

Affected domains and subdomains will fall back to any other active certificate covering the hostnames on the expiring certificate.
