<header>Automatic renewal interval</header>
|

|
|
<p>Sets how often Webmin should request a replacement certificate from the ACME
|
|
provider.</p>
|
|
|
|
<p>For hostname certificates, a renewal interval measured in months is usually
|
|
appropriate. You can also choose days if you want Webmin to rotate the
|
|
certificate more frequently.</p>
|
|
|
|
<p>IP address certificates are issued as short-lived certificates by CAs such as
|
|
Let's Encrypt. Let's Encrypt currently makes these certificates valid for
|
|
160 hours, just over six days, and requires IP address certificates to use the
|
|
short-lived profile because IP addresses can change ownership more often than
|
|
domain names.</p>
|
|
|
|
<p>For IP address certificates, Webmin defaults to days and using 1 or 2 days
|
|
is recommended so there is time to retry before the certificate expires. If
|
|
Webmin is managing automatic renewal, the interval must be no more than 5 days.
|
|
Manual renewal remains an administrator choice, especially if renewal is handled
|
|
by separate automation or another operational policy.</p>
