"Connect time out" error for jClouds via proxy

I am trying to run a simple program of jcloud. The program is as follows:

String provider = "openstack-nova";
String identity = "Tenant:usename"; // tenantName:userName
String credential = "pass";

novaApi = ContextBuilder.newBuilder(provider).endpoint("http://openstack.infosys.tuwien.ac.at/identity/v2.0")
    .credentials(identity, credential).modules(modules).buildApi(NovaApi.class);
regions = novaApi.getConfiguredRegions();

The openstack.infosys is connect via SOCKS proxy on port 7777. I have also enlisted the same on eclipse(Window->Preferences->General->Network Config->SOCKS(Manual)) . However, everytime I run the code I get the following error:

ERROR o.j.h.i.JavaUrlHttpCommandExecutorService - Command not considered safe to retry because request method is POST:

Which is then caused by

Caused by: java.net.SocketTimeoutException: connect timed out

I am able to access the horizon web interface of the same without any issues.

Can someone please help me in understanding what is the possible problem.
