Connection refused [Tarantool + java client]

Question

When i'm trying to connect to tarantool server i get the following error:

Exception in thread "main" java.net.ConnectException: Connection refused: connect at java.net.DualStackPlainSocketImpl.connect0(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:79) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at java.net.Socket.connect(Socket.java:538) at java.net.Socket.(Socket.java:434) at java.net.Socket.(Socket.java:211) at TarantoolKt.main(Tarantool.kt:37)

My code:

class Tarantool {
    val client: TarantoolClient

    init {
        val config: TarantoolClientConfig = TarantoolClientConfig()
        config.apply {
            username = "test"
            password = "test"
        }

        val socketChannelProvider: SocketChannelProvider = SocketChannelProvider { _, p1 ->
            when(p1) {
                null -> {
                    println("Trying to connect . . .")
                    SocketChannel.open(InetSocketAddress("192.168.1.254", 3301)) // <- error
                }
                else -> {
                    p1.printStackTrace(System.out)
                    null!!
                }
            }
        }

        client = TarantoolClientImpl(socketChannelProvider, config)
    }
}

fun main(args: Array<String>): Unit {    
    val client: Tarantool = Tarantool()
    println(client.client.isAlive)
}

I get the same error when i'm trying to use different ip

It's the same as in tutorial here: https://github.com/tarantool/tarantool-java/

I'd also created the test user using this commands:

box.schema.user.create('test', { password = 'test' })
box.schema.user.grant('test', 'execute,read,write', 'universe')

I use docker for tarantool and i tried to ping IPs from windows 7 cmd and it works.

Thank you!
