.net driver doesn't connect new graph traversal source

[harunsolidatus]

I try to reach new graph's GraphTraversalSource but it doesn't recognize it. Here is my steps

1. Configuration in janusgraph-server.yaml

graphs: {
  ConfigurationManagementGraph: conf/janusgraph-berkeleyje-server.properties
}

2. Groovy script is

def createNewGraph(graphName)
{    
    map = new HashMap<String, Object>();
    map.put("storage.backend", "berkeleyje");
    map.put("storage.hostname", "127.0.0.1");
    map.put("graph.graphname", graphName);
    map.put("storage.directory", "/var/lib/janusgraph/"+graphName);
    ConfiguredGraphFactory.createConfiguration(new MapConfiguration(map));
}

3. Call groovy script and see the new graph
   

4. Try to connect that graph with

_remoteConnection = new DriverRemoteConnection(_gremlinClient, "test");
_g = AnonymousTraversalSource.Traversal().WithRemote(_remoteConnection);

When I want to make operation with traversal object ( like _g.V().Count().Next()) it returns

Gremlin.Net.Driver.Exceptions.ResponseException: InvalidRequestArguments: The traversal source [test] for alias [g] is not configured on the server.

What should I do to make that graph recognizable for the .net driver?
