ERROR_IPSEC_IKE_DH_FAILURE - 13864 (0x3628)
Diffie-Hellman failure.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_IPSEC_IKE_DH_FAILURE error code indicates a failure in the Diffie-Hellman key exchange process during Internet Key Exchange (IKE) negotiations for IPsec. This error typically occurs when there is an issue with the cryptographic parameters or the security context used during the IKE phase.
Error Details
The ERROR_IPSEC_IKE_DH_FAILURE error code, 13864 (0x3628), signifies that a problem has occurred in the Diffie-Hellman key exchange mechanism. This can include issues such as incorrect parameters, corrupted data, or unsupported operations.
Usage Context
This error is commonly encountered during the establishment of IPsec security associations through IKE negotiations. It may occur when there are discrepancies between the cryptographic algorithms and parameters used by the two endpoints involved in the negotiation process.
Developer Interpretation
When encountering this error, developers should consider the following aspects:
- Parameter Validation: Ensure that all cryptographic parameters, such as Diffie-Hellman group identifiers and key exchange algorithms, are correctly specified and supported by both parties.
- Security Context: Verify that the security context used in the IKE negotiation is valid and consistent with the expected configuration.
- Data Integrity: Check for any potential corruption or tampering of data during the key exchange process.
