Невозможно подключиться к серверу RCON

Question

Я хочу создать небольшой инструмент Swift для управления моими Rust серверами.После многих попыток я не могу связаться с сервером RCON .

. Я могу успешно использовать класс Stream для подключения к серверу, но когда я пытаюсь отправить пакет,Я не получаю никаких откликов от сервера, кроме HasSpaceAvailable.

. Я думаю, что хорошо выполнил рекомендации, касающиеся протокола, но, к сожалению, безуспешно.

let host = "..."
    let port = ... 
    let password = "..."
    var inStream: InputStream?
    var outStream: OutputStream?
    var buffer = [UInt8](repeating: 0, count: 200)

    func stream(_ aStream: Stream, handle eventCode: Stream.Event) {
        switch eventCode {
        case Stream.Event.endEncountered:
            // End of connection, connection stopped by server
            // Close the streams and remove from Runloop
            inStream?.close()
            inStream?.remove(from: RunLoop.current, forMode: .default)
            outStream?.close()
            outStream?.remove(from: RunLoop.current, forMode: .default)

            print("End of connection, connection stopped by server")
//            isConnected = false

        case Stream.Event.errorOccurred:
            print("ErrorOccurred")
            // Error occured, failed to connect on server
            // Close the streams and remove from Runloop
            inStream?.close()

            outStream?.remove(from: RunLoop.current, forMode: .default)

//            isConnected = false

        case Stream.Event.hasBytesAvailable:
            print("bytes")
            // Has bytes avaible
            // Check the inStream
            if aStream == inStream {
                // read the stream and get into buffer
                inStream!.read(&buffer, maxLength: buffer.count)
                // cast buffer to string whith utf8 encoding

//                let bufferStr = NSString(bytes: &buffer, length: buffer.count, encoding: String.Encoding.utf8.rawValue)! as String
//                print(bufferStr)
            }
        case Stream.Event.hasSpaceAvailable:
            print("HasSpaceAvailable \(outStream!.hasSpaceAvailable)")
        case Stream.Event.openCompleted:
            print("Connected to server")
