OkHttp WebSocket RejectedExecutionException when try to restart

I have this client:

OkHttpClient okHttpClient = new OkHttpClient.Builder()
            .pingInterval(Duration.ofMinutes(3))
            .readTimeout(Duration.ofMillis(0))
            .build();

And this methods for start and stop:

private WebSocket webSocket = null;
private MyListener wsListener = null;

private void start(){

    if(webSocket != null){ return; }

    wsListener = new MyListener();

    Request request = new Request.Builder()
        .url("wss://stream.binance.com:9443/ws")
        .build();

    webSocketBinance = okHttpClient.newWebSocket(request, wsListener); //here triggers error

}

private void stop(){

    if(webSocket == null){ return; }

    webSocket.close(1000, "{"reason": "With love"}");
    webSocket= null;

    okHttpClient.dispatcher().executorService().shutdown();
    okHttpClient.connectionPool().evictAll();

    wsListener = null;

}

Sometimes I want to restart the connection like this:

start();

Thread.sleep(10_000);

//restart connection
stop();
start(); //here triggers the error

But at start() I get this error:

java.io.InterruptedIOException: executor rejected

Answer

The solution in my case was to create a new OkHttpClient and WebSocket every time when I want to restart.
