Start with the generate-client-from-indigo-endpoint Ant target and reproduce the shown wsimport command against the HostedClient.svc?wsdl URL. Inspect how wsimport obtains the WSDL and handles SOCKS proxy settings, then verify that the interop client generation succeeds without the connection-refused failure.
