ES 1.4.2 - MasterNotDiscovered Exception with Java Node Client

Elastic Stack Elasticsearch
1

I am trying to connect with a Java application from localhost to my
elasticsearch cluster on a root server. My problem is that the java client
is not able to get a connection.

Ports 9200-9299 and 9300-9400 are opened on the root server(groupelite.de).

I configured my elasticsearch cluster to use unicast discovery and set its
inet ip address as "network.host".
This is how I instantiate my client:

NodeBuilder.nodeBuilder()
  .clusterName("neeedo-es")
  .settings(ImmutableSettings.settingsBuilder()
    .classLoader(classOf[Settings].getClassLoader)
    .put("discovery.zen.ping.unicast.hosts", "groupelite.de:9300")
    .put("node.name", "neeedo-client"))
  .client(true)
  .data(false)
  .node()

And this is my elasticsearch.yml

The firewall on the server should be turned off. You can also reach es with
http:
http://www.groupelite.de:9200/

The server is running ubuntu 14.04. Elasticsearch version is 1.4.2 on
client and server.

Iam not very used to networking stuff but I hope to get some ideas from you
guys what is wrong.

DO NOT leave your cluster open to anyone on the internet, this is a REALLY
BAD idea!!

There is no data on it right now and also only limited diskspace for es. I
am planning to tryout Shield and will secure it later on. But first of all
I want to be able to get a connection to it. :-/
Anyways thanks for your advice.

I have found out, that it works when I use a Transport Client. Does this
give any hint what is wrong with the Node Client Configuration? Both
clients are using the elasticsearch binary protocol and port 9300 right?
