What does Windows error code 13830 (ERROR_IPSEC_IKE_PROCESS_ERR_SA) mean?

ERROR_IPSEC_IKE_PROCESS_ERR_SA

ERROR_IPSEC_IKE_PROCESS_ERR_SA identifies a failure while parsing the IKE Security Association payload. That payload carries the high-level security-association proposal structure used to negotiate protection.

Start with the SA payload structure and then follow any more specific proposal or transform error. This ordering prevents a malformed peer proposal from being misdiagnosed as a generic reachability or credential problem.

What to check

• Capture the exchange and compare the offered IKE proposals with the local policy.
• Check whether the peer is using an unsupported IKE version or proposal layout.
• Look for a more specific transform, proposal or payload error immediately before or after this code.
