SSL certificate issuance failure can occur due to several reasons. Common issues include:
Domain Validation Failure: The Certificate Authority (CA) cannot verify that the applicant owns or controls the domain. For example, if the DNS records are incorrect or not updated, the CA cannot confirm control.
Organization Validation Failure: For Organization Validation (OV) certificates, the CA cannot verify the organization's identity or physical presence. This might happen if the provided business details are inaccurate.
Incorrect or Incomplete Information: Providing wrong information during the certificate request process, such as misspelling the domain name or entering incorrect company details, can lead to issuance failure.
Insufficient Certificate Signing Request (CSR) Information: If the CSR is missing required fields or contains errors, the CA cannot process the request correctly.
Policy or Compliance Issues: Certain certificates have specific requirements that must be met. For instance, Extended Validation (EV) certificates require strict verification processes that might fail if the applicant does not meet all criteria.
Technical Issues with the CA: Sometimes, the issue might be on the CA's side, such as server errors or maintenance activities, which can temporarily prevent certificate issuance.
Timeouts: If the validation process takes too long, it might expire, leading to a failure in certificate issuance.
