Why is ConnectException: Connection refused: connect exception thrown from HttpURLConnection.getResponseCode()?

HttpURLConnection con = (HttpURLConnection) obj.openConnection();
con.setRequestMethod("POST");

I'm trying out openstack4j, and I've run into a problem I don't know what could be causing.
Authentication to the cloud went smoothly:
OSClient os = OSFactory.builder()
.endpoint("http://xxx.xxx.xxx.xxx:yyyyy/v2.0")
.credentials(username,password)
.tenantName("admin")
.perspective(Facing.PUBLIC)
.authenticate();
However, once os is instanciated, I try running the following line:
List<? extends Flavor> flavors = os.compute().flavors().list();
And I get an ConnectionException{message=java.net.ConnectException: Connection timed out: connect, status=0}
What could be causing this?
Thanks in advance.

When I test an RMI client and server with the class files it works without any issue on two different machines. Now when I do the same thing with a jar the client fails to connect to the RMIRegistry on the server. Then when I test with the jar on the same machine, the client can connect to the server (even over the network ip and not localhost).
I suspect this has something to do with the RMI registry, but i'm a total novice at RMI, so I have no clue...
I create an RMIRegistry like so:
rmiregistry = LocateRegistry.createRegistry(ServiceConstraints.REGISTRY_PORT);
rmiService = (RmiSubjectService) UnicastRemoteObject.exportObject(this,
ServiceConstraints.REGISTRY_PORT);
rmiregistry.rebind("RmiService", rmiService);
The client connects like this:
remoteService = (RmiSubjectService) Naming.lookup("/" + host + ":"+ port + "/RmiService");
The error I get on the client when running with a jar:
java.rmi.ConnectException: Connection refused to host: 192.168.2.132; nested exception is:

The problem did turn out to be the network. Specifically it was that I didn't realize that my firewall was blocking the socket, so I could not connect.
I am trying to connect a client (which is behind the company's proxy) to a server (JBoss AS 5.0) which is hosting an application (JavaFX). And I am facing the following error.

However, if i am trying to access the application(JavaFX) locally, i have no problem loading the application. Do i need to configure any proxy for the client to access the server?
Any advice on solving this will be greatly appreciated.
Thanks in advance.
Kevin
It is a feature of JBoss check this document
start JBoss by
./run.sh -b 0.0.0.0
or
run.bat -b 0.0.0.0
Seems like Jboss server is not running.You need to start server.

If anybody knows any API for translation, please tell me.
As suggested by the guy on JavaRanch, there is an issue with the connection to the API
Somewhere you will have specified a URL to connect to, something is blocking that, check you can access that address via ping
