How often does AutoSSL attempt to renew

Question

How soon to expiry does AutoSSL renew a certificate?

Answer

Each AutoSSL provider may wait for a specific amount of time to replace an AutoSSL-provided certificate before it expires. For example:

• AutoSSL attempts to renew certificates that cPanel, L.L.C. provides when they expire within 3 days.

• AutoSSL attempts to renew certificates that Let’s Encrypt provides when they expire within 29 days.

Hostname certificates are handled differently:

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