This steps in this document only apply to cPanel & WHM version 11.54 and earlier.

This article explains why you received an email notification to reset your SSL certificates for your cPanel services.

Why you received an email notification to reset your cPanel SSL certificates

If you do not reset an SSL certificate before it expires, it will become invalid. When the certificate for your cPanel service expires within 30 days, your server sends you reminder email notifications. The system automatically renews self-signed certificates when they expire, or you can renew the certificates at any time to stop the email notifications. For example, you might receive the following email:


Subject: "The SSL certificate for cPanel on will expire in less than 30 days."
Body: Your server's SSL certificate for cpanel will expire in less than 30 days. You need to install a new certificate as soon as possible. You can install a new certificate using WHM's "Manage Service SSL Certificates" interface: (Home >> Service Configuration >> Manage Service SSL Certificates).


You can modify your email notification preferences. For more information, read our Contact Manager documentation.

How to reset self-signed SSL certificates


Only perform the following steps to reset a self-signed certificate and not a signed certificate. If you perform these steps for a signed certificate, you will replace a signed certificate with a self-signed certificate. When a user navigates to a website with a self-signed certificate, they receive a warning message. We strongly recommend that you use a signed certificate. For more information, read our Purchase and Install an SSL Certificate documentation.


When you reset the SSL certificate for Calendar, cPanel, Webdisk, Webmail, and WHM Services, the system will log you out of WHM. Log in again to reset additional certificates.

To reset any cPanel service's self-signed SSL certificate, perform the following steps:

  1. Log in to WHM as the root user.
  2. Navigate to WHM's Manage Service SSL Certificates interface (WHM >> Home >> Service Configuration >> Manage Service SSL Certificates).
  3. In the Actions column, click Reset Certificate for the desired service.

The new expiration date will display in the Certificate Expiration column.
