Automatic domain control validation (DCV) check
DigiCert's automatic DCV check, also called DCV polling, eliminates the need for you to run validation checks manually when using random-value-based DCV methods. CertCentral performs the DCV check automatically. However, you can still run a manual check when required.
DCV polling applies to the following DCV methods:
How DCV polling works
DCV polling begins immediately when you submit a domain for validation and runs for ten days.
After you place the required validation artifact, DigiCert checks periodically for the random value in DNS or the validation file on the web server. When DigiCert detects the artifact and confirms it matches the random value, domain validation completes automatically.
If you need immediate confirmation rather than waiting for the next polling cycle, trigger a manual check from the Order details page or Domain details page in CertCentral.
DCV polling cadence
DCV polling runs according to the following schedule:
Interval | Frequency | Duration |
|---|---|---|
1 | Every 1 minute | First 15 minutes |
2 | Every 5 minutes | 1 hour |
3 | Every 15 minutes | 1 day |
4 | Every 1 hour | 10 days |
When interval four finishes, CertCentral stops checking for the random value. If the random value is not yet in place, run the validation check manually from the domain details page or the Order details page. Running a manual check restarts DCV polling for another ten days.
Common reasons polling does not complete
DNS propagation is incomplete. The record is not yet publicly resolvable.
The validation file is not accessible on port 80. Check firewall rules and confirm the file path is correct.
The DigiCert-generated random value has expired. Generate a new token and repeat the record creation or file placement step.
The record value was modified. The random value must be placed exactly as provided by DigiCert.
