AutoSSL certificates are not installed automatically on new domains

Symptoms

After adding a new domain to a cPanel account, an AutoSSL certificate is not automatically installed on it.

Cause

With the release of cPanel v134.0.3, a unified SSL interface was added to cPanel, combining the SSL/TLS, SSL/TLS Status, and SSL/TLS Wizard interfaces. As part of this update, new domains no longer have a free Let's Encrypt certificate generated for them.

Resolution

With the unified SSL interface introduced in cPanel v134.0.3, new domains no longer have a Let's Encrypt certificate issued automatically. When setting up SSL for a new domain, cPanel now explicitly prompts the user to review and accept the Let's Encrypt Terms of Service before a certificate can be issued. This ensures users are aware of and consent to the terms before a certificate is generated on their behalf.
Free Let's Encrypt certificates remain available and can be requested via the Wizard tab of the new SSL/TLS Certificates page.
If you would like to restore automatic SSL certificate creation for new domains — effectively accepting the Let's Encrypt Terms of Service on behalf of your users — you can do so by adding the following to your /var/cpanel/panel.ini file (create it if it does not exist):

CONFIG_TEXT: [global]
autossl.exclude_new_domains = false

Note: By configuring this option, you as the hosting provider take responsibility for ensuring that your users are informed of and in agreement with the Let's Encrypt Terms of Service.
