ERROR_IPSEC_IKE_REQUIRE_CP_PAYLOAD_MISSING - 13900 (0x364C)
Require configuration payload missing.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_IPSEC_IKE_REQUIRE_CP_PAYLOAD_MISSING error code indicates that a required configuration payload is missing during the Internet Protocol Security (IPsec) Internet Key Exchange (IKE) negotiation process. This error typically arises when an expected configuration parameter or data element necessary for establishing secure communication channels between two endpoints is not present.
Error Details
This specific error is related to the IPsec/IKE protocol stack, which is responsible for negotiating and managing security associations in network communications. The CP payload (Configuration Payload) contains critical information required for configuring the security parameters of an IPsec tunnel or connection. When this payload is missing during the negotiation process, it results in the aforementioned error.
Usage Context
This error can occur in various scenarios where IPsec/IKE negotiations are initiated between two network endpoints. Common contexts include setting up secure tunnels, establishing remote access connections, and configuring network security policies that rely on IPsec/IKE for encryption and authentication.
Developer Interpretation
Developers should interpret this error as an indication that a necessary configuration element is missing in the negotiation process. This could be due to incorrect or incomplete input parameters, misconfiguration of the IPsec/IKE settings, or issues with the security policies being applied. The presence of this error suggests that the system cannot proceed with the intended operation until the missing payload is provided.

FAQ
Q: What does the ERROR_IPSEC_IKE_REQUIRE_CP_PAYLOAD_MISSING error mean?
A: This error indicates that a required configuration payload is missing in an IPsec/IKE negotiation process. It suggests that necessary security parameters or data elements are not present, preventing the establishment of secure communication channels.
Q: How can I resolve this issue?
A: Ensure that all required configuration payloads are correctly specified and included in the IKE negotiation process. Verify that the IPsec/IKE settings and security policies are properly configured to include all necessary parameters.
Summary
The ERROR_IPSEC_IKE_REQUIRE_CP_PAYLOAD_MISSING error is a specific indication of missing configuration data during an IPsec/IKE negotiation. Developers should focus on ensuring complete and correct input parameters to avoid this error, thereby facilitating successful establishment of secure network connections.
