ERROR_IPSEC_IKE_PROCESS_ERR_PROP
ERROR_IPSEC_IKE_PROCESS_ERR_PROP means the proposal portion of the IKE security-association exchange could not be processed. A proposal describes candidate cryptographic protection settings.
What to check for ERROR_IPSEC_IKE_PROCESS_ERR_PROP
- Compare the IKE and IPsec proposal sets on both peers.
- Check whether an intermediate gateway is rewriting or filtering negotiation traffic.
- Use a packet capture to identify the proposal that was rejected or malformed.

Where the result is returned
This result is Win32 system error 13831 (0x00003607) from winerror.h. AllStat describes it as “Error processing Proposal payload”. The code is useful only together with the API that failed, because multiple Windows components can reuse system-error values while imposing different retry and cleanup rules.
Diagnostic sequence
- Call GetLastError immediately after the failing API and save this result, the function name, all relevant flags, and the target path, handle, service, device, account, or policy object.
- Capture the component log that owns the ipsec / ike / process / err / prop operation and retain the original numeric value before a framework converts it to an HRESULT or exception.
- compare preconditions with the API documentation and reproduce with a minimal request before changing system-wide configuration.
Retry this result only after the resource or state named in “Error processing Proposal payload” has changed. For invalid parameters, unsupported formats, missing objects, policy restrictions, and access failures, correct the input or configuration instead of immediately repeating the same call.
