ERROR_IPSEC_IKE_INVALID_PAYLOAD

ERROR_IPSEC_IKE_INVALID_PAYLOAD is a protocol-level error indicating that an IKE payload was malformed or inconsistent with the negotiation. It is broader than the individual PROCESS_ERR_* codes, which identify the payload category.

What to check for ERROR_IPSEC_IKE_INVALID_PAYLOAD

  • Capture the negotiation and identify the message, payload type, length and IKE version.
  • Check whether a VPN appliance, NAT, load balancer or another middlebox is sending the reply instead of the expected peer.
  • Look for a more specific payload-processing error that identifies the affected SA, transform, certificate, identity or notify data.
