jenkins plugin connection refused

Question

I have the following snippet that is part of a Jenkins plugin listed below. The problem is that when running it, I am getting "connection refused" . I am using a Tomcat web server on Ubuntu 16.0.4. It is being hosted on vultr.

The error message (from the console) is listed below - the connection is refused so nothing else can take place

I have also tried the actual IP address and "localhost"

Building WAR file for Project...
Opening WaveMaker project: Project
Sending WaveMaker a message: {"params":["Project"],"method":"openProject","id":5}

)

The code being called is as follows:

        private boolean sendWaveMakerRequest(String serviceUrl,
                DefaultHttpClient client, String json, String expectedResponse,
                BuildListener listener) throws UnsupportedEncodingException,
                IOException, ClientProtocolException {
            HttpPost postRequest = new HttpPost(serviceUrl);


        listener.getLogger().println("Sending WaveMaker a message: " + json);

        HttpResponse response = sendRequest(client, json, postRequest);

        if (!checkWaveMakerStatus(listener, response)) {
            return false;
        }

        if (!checkWaveMakerReason(listener, response)) {
            return false;
        }

        return checkJsonResponse(expectedResponse, listener, response);
    }

Question: What can I do to solve the problem? TIA

You can configure the proxy server that Jenkins will use by going to Manage Jenkins > Manage Plugins > Advanced. This is preferred over setting JVM properties.
