ERROR_IPSEC_IKE_CRL_FAILED - 13817 (0x35F9)

Certificate Revocation Check failed.

Updated: Feb 21, 2026

Technical Background

The error code ERROR_IPSEC_IKE_CRL_FAILED (13817, 0x35F9) is a specific error related to the Internet Key Exchange (IKE) protocol in the IP Security (IPSec) subsystem. This error indicates that a certificate revocation check failed during the IKE negotiation process.

Error Details

The ERROR_IPSEC_IKE_CRL_FAILED error occurs when the system encounters an issue with the certificate revocation list (CRL) during the establishment of an IPSec security association using the IKE protocol. This typically happens when the CRL is either missing, corrupted, or not accessible.

Common Causes

  • Invalid Certificate Revocation List: The CRL used in the negotiation process may be invalid or outdated.
  • CRL Accessibility Issues: The system might not have access to the required CRL due to network issues or incorrect configuration.
  • Corrupted Data: The CRL data itself could be corrupted, leading to a failure during validation.

Real-World Context

This error is commonly encountered in environments where IPSec is used for secure communication between hosts. It can occur when the IKE negotiation process fails due to issues with certificate revocation checks, which are crucial for ensuring that revoked certificates are not accepted as valid.

Is This Error Critical?

The criticality of this error depends on the context and the specific application of IPSec in your environment. If the security association is essential for secure communication, then this error could be considered critical as it may prevent the establishment of a secure connection.

How to Diagnose

To diagnose this issue, follow these steps:

  1. Review Operation Context: Ensure that all necessary CRLs are available and accessible in the expected locations.
  2. Validate Parameters: Check if the parameters used for the IKE negotiation process are correct and up-to-date.
  3. Confirm Object Types: Verify that the certificate objects being checked are of the correct type and format.
  4. Verify Input Data: Ensure that the CRL data is not corrupted or outdated.
  5. Check Limits or Constraints: Confirm that there are no system limits or constraints preventing access to the CRL.

How to Resolve

To resolve this issue, consider the following steps:

  1. Correct Parameter Usage: Ensure that all parameters used in the IKE negotiation process are correct and up-to-date.
  2. Adjust Operation Context: If necessary, adjust the operation context to ensure that the system has access to the required CRLs.
  3. Restore Data: If the CRL data is corrupted, restore it from a backup or obtain an updated version.
  4. Retry Operation with Valid Inputs: Attempt to establish the security association again using valid inputs and parameters.

Developer Notes

Developers should ensure that their applications handle this error gracefully by providing appropriate fallback mechanisms or user notifications when encountering ERROR_IPSEC_IKE_CRL_FAILED. Additionally, they should implement robust certificate management practices to prevent such errors from occurring.
