How often does AutoSSL attempt to renew

Question

How soon to expiry does AutoSSL renew a certificate?

Answer

Each AutoSSL provider renews their certificates on different intervals:

• AutoSSL will attempt to renew certificates provided by the default "Let's Encrypt" provider within 29 days of expiry.
• AutoSSL will attempt to renew certificates provided by the "cPanel (Powered by Sectigo)" provider within 15 days of expiry.
• If "Allow AutoSSL to replace invalid or expiring non-AutoSSL certificates" is enabled, AutoSSL will attempt to request free certificates from your configured provider 3 days before expiry to replace any non-AutoSSL-provided certificates.

Hostname certificates are handled differently:

• Hostname certificates will be renewed within 3 days of expiry.
