SrtCommonInputSettings.onConnectionRejected property

A connection refused at the CRYPTO layer by the (route, user) passphrase table — the handshake was rejected before could run, so this is the only visibility the application gets (probe / DoS auditing). Reasons: "unknown_route" | "unknown_user". NB a WRONG passphrase fails later in SRT’s key-material exchange and produces no event; those attempts appear only in the engine’s srt logs.

Signature:

onConnectionRejected?: (rejection: {
        streamId: string;
        route: string;
        user?: string;
        remoteHost: string;
        reason: string;
    }) => void;
