Run automatic domain control validation checks

CertCentral periodically checks for validation artifacts when validation methods require DNS records or HTTP validation files. Automatic checks allow DigiCert to validate domains without a manual validation attempt.

During each check, DigiCert verifies that the required validation artifact is publicly accessible and matches the DigiCert-generated random value for the domain.

Automatic checks apply to the following validation methods:

  • DNS TXT record

  • DNS CNAME record

  • HTTP practical demonstration

  • ACME HTTP-01 challenge

  • ACME DNS-01 challenge

When automatic checks complete successfully:

  • The domain validation status updates and the reuse period resets.

  • Certificate issuance, renewal, and replacement proceed without interruption.

When automatic checks do not complete:

Confirm the following:

  • The validation artifact is publicly accessible

  • The artifact matches the value displayed in CertCentral

  • DNS propagation is complete for DNS-based methods

  • Port 80 is accessible for HTTP-based methods

  • The DigiCert-generated random value has not expired

If the random value has expired, retrieve a new value from the domain details page in CertCentral and update the validation artifact.

Validate domains and perform DNS validation checks to use DNS integrations to automate domain validation and maintain continuous reuse
