FWP_E_INCOMPATIBLE_AUTH_METHOD

FWP_E_INCOMPATIBLE_AUTH_METHOD means an IPsec authentication method is valid in isolation but cannot be used with the selected policy type.

What to verify

  • Review the policy type and the authentication methods configured for both endpoints.
  • Check that certificate, Kerberos, pre-shared-key, or other configured authentication is valid for the negotiation mode being used.
  • Capture IKE events while reproducing the failure to distinguish an invalid local policy from remote-peer negotiation failure.
