ERROR_HASH_NOT_PRESENT - 15301 (0x3BC5)
The hash requested from the server is not available or no longer valid.
Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_HASH_NOT_PRESENT (15301, 0x3BC5) indicates that a requested hash value from the server is either not available or no longer valid. This error typically arises in scenarios where cryptographic hashes are expected to be present but are missing.
Error Details
This error can occur in various contexts involving data integrity checks and server communication, particularly when verifying the authenticity of files or other data entities using hash values. The absence of a required hash could indicate an issue with the server's response, the client's request parameters, or the overall integrity of the data being processed.
Usage Context
The error is commonly encountered in applications that rely on cryptographic hashes for verifying file integrity, such as software distribution systems, content management services, and security tools. It may also appear in scenarios where hash values are used to ensure data consistency across different systems or components.
Developer Interpretation
When encountering ERROR_HASH_NOT_PRESENT, developers should consider the following aspects:
- Server Response: Verify that the server is correctly providing all expected hash values.
- Request Parameters: Ensure that the client's request includes all necessary parameters to retrieve the required hashes.
- Data Integrity: Check for any corruption or modification of data that could affect the availability of the requested hash value.
