CRYPT_E_VERIFY_USAGE_OFFLINE
The subject-usage verifier could not complete its check because a required server or online resource was unavailable.
What to check for CRYPT_E_VERIFY_USAGE_OFFLINE
- Identify the remote resource required by the policy or usage-verification component.
- Check DNS, proxy, firewall, and service availability from the security context that performs verification.
- Keep this separate from certificate revocation unless the logs show that the unavailable resource is specifically a revocation endpoint.
Microsoft: CertVerifyCertificateChainPolicy
Microsoft: CertVerifyRevocation
Diagnostic discriminator: Check whether usage-policy verification requires an online resource that is currently unavailable. This status is an offline verification path, not proof that the certificate usage is invalid.
