WU_E_METADATA_TIMESTAMP_TOKEN_NODATA
WU_E_METADATA_TIMESTAMP_TOKEN_NODATA means the metadata-verification timestamp-token cache contains no usable entries. By itself, that can be normal if the client is expected to fetch evidence online; it becomes a failure when a required refresh cannot occur.
What to check
- Check the next log entries to see whether Windows Update tried an online token refresh.
- Verify that the client can reach the configured update metadata service without TLS interception.
- In an offline environment, confirm that the scan method and signed scan package are supported for the required task.
