Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the wp-expand-tabs-free domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

How do I enable Let’s Encrypt for AutoSSL on WHM? | Advanced Internet Technologies

After the release of cPanel & WHM version 58 there has been the addition of an AutoSSL feature. This feature will provide Domain Validated SSLs for domains on your WHM & cPanel servers (VPS and Dedicated Servers). Upon release, cPanel (powered by Comodo) SSL certificates are allowed, however cPanel & WHM servers running version 58.0.17, and above, can now also use Let’s Encrypt as an SSL provider. More information on Let’s Encrypt can be found athttps://letsencrypt.org/

Step 1: Initial Configuration

The server should be running cPanel & WHM version 58.0.17, or higher. Also, it is recommend to have ssh access to your server in order to perform these steps. If you are not able to ssh to the server, you should ensure ssh is enabled, and you configured Putty or another ssh client to connect to your server securely via a commandline interface.

Step 2: Installing and Enabling Let’s Encrypt Auto SSL

In order to install the Let’s Encrypt AutoSSL provider plugin you will simply log in to the server as the root user via SSH and execute the following command:# /scripts/install_lets_encrypt_autossl_provider

Running this will add and install the necessary RPM files in order to support Let’s Encrypt as an AutoSSL provider. The command should yield results similar to the following:Installed the cpanel-letsencrypt RPM! AutoSSL can now use Let’s Encrypt.

Step 3: Confirming Installation

To double check that this has been successful you can simply pull up WHM and load the “Manage AutoSSL” page. On this page, you’ll see “Let’s Encrypt” as an option for AutoSSL Providers. If it is not installed, please contact AIT Support for further review of your configurations. You can submit a trouble ticket under your My Account interface. Please be sure to specifiy the root login information for your server when submitting the ticket.

One thing to keep in mind is that there are some domain and subdomain limits that are enforced by Let’s Encrypt. More details on that can be found in cPanel documentation here:Manage AutoSSL – Domain and rate limits.
