cPanel provides two built-in options for provisioning SSL certificates. Both are free and work very well to install domain-validated certificates. At times, there may be a need to switch from Let's Encrypt to the more seamless approach of AutoSSL. This guide will cover the steps needed in the process.
The first step is to log into your cPanel account. Next you'll want to find the Lets Encrypt™ SSL feature which is under the SECURITY section.
There will be a listing of all domains which have a Let's Encrypt certificate installed on them. Clicking Remove under Actions will uninstall the certificate.
A warning will appear asking if you are you sure you wish to permanently remove the certificate for the listed domain. Click the Remove Certificate button.
Once completed, a notification will let you know that the certificate has been removed.
Next, click on the SSL/TLS Status icon which is also under the SECURITY section in cPanel.
On the following page, you should see all your domains listed. If an AutoSSL certificate has not yet been installed, there will be a notification under Certificate Status No certificate available. AutoSSL will attempt to secure the domain the next time it runs.
AutoSSL typically runs every few hours through a background process managed by the server. However it's possible to install the certificate right away by selecting the domain and then clicking the Run AutoSSL button.
The button will change to a notification letting you know that the certificate provisioning is in progress. This can take a few minutes.
Once completed, you'll be taken back to the SSL/TLS Status page and there will now be a green lock in front of the domain name letting you know the certificate has been installed and when it expires. The certificates are good for 90 days and will auto-renew so no further action is needed in this regard.
