ERROR_IPSEC_IKE_PROCESS_ERR_KE - 13833 (0x3609)

Error processing KE payload.

Updated: Feb 21, 2026

Technical Meaning

This error code indicates a failure in processing the KE (Key Exchange) payload during the Internet Key Exchange (IKE) negotiation process. IKE is used for establishing and maintaining security associations between two endpoints in IPsec.

Error Details

The KE payload is part of the IKEv1 or IKEv2 protocol, which is responsible for exchanging cryptographic keys and other parameters necessary to establish a secure connection. The error suggests that there was an issue with how this specific payload was processed during the negotiation process.

Usage Context

This error typically occurs in scenarios where IPsec services are being configured or established between two endpoints. It can be encountered when setting up a new security association, renewing existing ones, or troubleshooting issues related to IPsec connections.

Developer Interpretation

When this error is returned, it signifies that the system encountered an issue while processing the KE payload during IKE negotiation. Developers should interpret this as a failure in key exchange and consider potential causes such as invalid parameters, incorrect object types, or corrupted data.

Common Causes

  • Invalid Parameter Values: Incorrect values passed to the IKE negotiation process could lead to errors.
  • Incorrect Object Types: The system might expect certain types of objects (e.g., keys, certificates) but receive others, leading to processing failures.
  • Corrupted Data: If the KE payload is corrupted or incomplete, it can result in this error.

Related Errors

  • Error_IPSEC_IKE_PROCESS_ERR_CERT: Indicates issues with certificate processing during IKE negotiation.
  • Error_IPSEC_IKE_PROCESS_ERR_KEY: Suggests problems with key management during the negotiation process.

FAQ

Q: What does this error mean?

A: This error indicates a failure in processing the KE payload during IPsec IKE negotiation, which can be due to invalid parameters or corrupted data.

Q: How common is this error?

A: The frequency of occurrence depends on the specific implementation and usage context. It may occur more frequently in environments with complex security configurations or when dealing with legacy systems.

Summary

Error_IPSEC_IKE_PROCESS_ERR_KE (13833, 0x3609) is a generic error indicating an issue with processing the KE payload during IPsec IKE negotiation. Developers should focus on validating parameters and ensuring data integrity to resolve this issue.
