AWS - XML-RPC Server

I am writing code to setup an AWS Server. I am able to test all the
values accurately using web_service_scaffold :test, but when I try to
connect by creating an XML-RPC client i am getting a timeout error =
execution expired

I am using delegated dispatching

web_service_name: update_shipping
method_name: update_product_status

I am trying to test the function by implementing an XML-RPC client to
connect with my web service

server =
XMLRPC::Client.new2(“http://localhost:3000/shipping/update_shipping”)
result = server.call(“UpdateProductStatus”, “packship”, “test”, 1, 2,
“product_pickedup”)

puts result

I am wondering if there is anything else I need to do to be able to
connect with this service. Does my local firewall have anything to do
with it not being able to connect. Again the service works perfectly by
going through the AWS test scaffold
