groovy unknown host exception with REST client

Question

The below code returns an exception even though the provided REST endpoint is up and valid. It is processed correctly as the DEBUG prompt shows the link of the GET request. It fails at the http.request line regardless of the REST endpoint provided. This is being executed by hitting Run 'MyScript' on intelliJ 14.1 .. Is there something missing to this piece of code?

import groovyx.net.http.ContentType

def http = new HTTPBuilder()

uri.path = '/ajax/services/search/web'
uri.query = [ v:'1.0', q: 'Calvin and Hobbes' ]
headers.'User-Agent' = "Mozilla/5.0 Firefox/3.0.4"
headers.Accept = 'application/json'

response.success = { resp, reader ->
    assert resp.statusLine.statusCode == 200
    println "Got response: ${resp.statusLine}"
    println "Content-Type: ${resp.headers.'Content-Type'}"
    println reader.text
}

    response.'404' = {
        println 'Not found'
    }
}
