The Pending Certificates section of the interface lists all of the SSL certificates that you have purchased from the cPanel Store. The system will automatically poll the certificate provider to determine whether each pending certificate is ready.
When a certificate is ready, the system will download that certificate and automatically install it on the site.
The cPanel Store will automatically email a copy of the certificate to the user. If the cPanel Store fails to redirect the user back to their account's SSL/TLS Wizard interface, the user can install the certificate manually.
The validation process for Organization Validated (OV) certificates and Extended Validation (EV) certificates takes between three and 30 days. The certificate issuer requires this time to validate the information about your business. EV certificates need more time to issue than OV certificates due to more stringent requirements.
Comodo will send you an email with additional validation instructions. Complete these instructions as soon as possible to avoid delays.
Although cPanel, Inc. will instantly issue a Domain-validated certificate (DV), the validation process can take up to 24 hours before the certificate is available for installation.
