WU_E_METADATA_TIMESTAMP_TOKEN_REFRESHONLINE
WU_E_METADATA_TIMESTAMP_TOKEN_REFRESHONLINE means the client attempted to retrieve timestamp evidence online because it was missing locally, but that refresh failed.
What to check
- Inspect the earlier WinHTTP, proxy, DNS, TLS, or endpoint errors that explain why the online refresh failed.
- Ensure the Windows Update metadata path is not intercepted by a TLS proxy; Microsoft documents certificate pinning for metadata connections.
- If the device is intentionally offline, use the supported offline-scan workflow and current signed scan package where applicable.
