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.

Diagnostic interpretation of CRYPT_E_VERIFY_USAGE_OFFLINE
CRYPT_E_VERIFY_USAGE_OFFLINE has the HRESULT value 0x80092029. AllStat records the condition as “Since the server was offline, the called function was unable to complete the usage check.”. For CRYPT_E_VERIFY_USAGE_OFFLINE, in practice, interpret that wording at the boundary owned by cryptography, certificate, trust, or key-provider processing, rather than treating the value as a generic Windows message.
Evidence to capture for CRYPT_E_VERIFY_USAGE_OFFLINE
- Record the exact COM method or Windows API, its input object, the calling thread, and the full 0x80092029 value before a wrapper converts it to an exception or Boolean result.
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions CRYPT_E_VERIFY_USAGE_OFFLINE or the crypt / verify / usage / offline operation.
- Preserve the first failure in the call chain; a later HRESULT can describe cleanup rather than the original crypt / verify / usage / offline condition.
Retry and recovery for CRYPT_E_VERIFY_USAGE_OFFLINE
Retry CRYPT_E_VERIFY_USAGE_OFFLINE only when the owning API documents a transient state or after the condition described as “Since the server was offline, the called function was unable to complete the usage check.” has changed. For CRYPT_E_VERIFY_USAGE_OFFLINE, configuration, policy, format, and authorization failures normally require correction first; an immediate loop can hide the original call site and add secondary errors.
