Check the status of your DV certificate order and use the DNS CNAME Record DCV method to demonstrate control over a domain in the order. See Domain Control Validation (DCV) methods for more information.
Demonstrate control over your domain by creating a DNS CNAME record containing a randomly generated token. The CNAME record is used to point token.domain to DigiCert (dcv.digicert.com).
In your CertCentral account, in the left main menu, go to Certificates > Orders.
On the Orders page, in the Order # column, select the order number link for the pending certificate order.
On the Order # details page, in the Order Status section, check the order's validation status (is the order waiting on domain validation to be completed?).
Under You Need To, select the Prove control over domains link.
In the Prove control of your domain window, in the Domain control validation (DCV) method dropdown, select DNS CNAME Record.
