How to use Ruby's XMLRPC::Client::new3 - ruby

Question

I'm trying to sort out how to use the new3 method of the XMLRPC::Client class. This is what I have:
#!/usr/bin/ruby
require "xmlrpc/client"
params = {
host: "https://192.168.1.2",
path: "rpc/api",
port: "443",
proxy_host: "",
proxy_port: "",
user: "username",
password: "password",
use_ssl: "true",
timeout: 300,
}
session = XMLRPC::Client.new3(params)
session.instance_variable_get(:#http).instance_variable_set(:#verify_mode, OpenSSL::SSL::VERIFY_NONE)
sys_ver = session.call('api.systemVersion')
users = session.call("user.listUsers", session)
If I use the new2 method the script will connect and return a 404 error. However, if I use the new3 it returns
/usr/lib/ruby/1.9.1/net/http.rb:762:in `initialize': Connection refused - connect(2) (Errno::ECONNREFUSED)
from /usr/lib/ruby/1.9.1/net/http.rb:762:in `open'
from /usr/lib/ruby/1.9.1/net/http.rb:762:in `block in connect'
from /usr/lib/ruby/1.9.1/timeout.rb:68:in `timeout'
from /usr/lib/ruby/1.9.1/timeout.rb:99:in `timeout'
from /usr/lib/ruby/1.9.1/net/http.rb:762:in `connect'
from /usr/lib/ruby/1.9.1/net/http.rb:755:in `do_start'
from /usr/lib/ruby/1.9.1/net/http.rb:750:in `start'
from /usr/lib/ruby/1.9.1/xmlrpc/client.rb:535:in `do_rpc'
from /usr/lib/ruby/1.9.1/xmlrpc/client.rb:420:in `call2'
from /usr/lib/ruby/1.9.1/xmlrpc/client.rb:410:in `call'
from sat_test.rb:24:in `<main>'
Am I using the new3 method properly?
Also, if I use the new method instead, do I need to set parameter=value for each parameter (proxy_host=, proxy_port=, etc)?

The problem seemed to be more with my script being coded wrong. This is what I have now:
#!/usr/bin/ruby
require "xmlrpc/client"
params = {
host: "REDACTED",
path: "/rpc/api",
use_ssl: "true",
user: "REDACTED",
pass: "REDACTED"
}
client = XMLRPC::Client.new3(params)
client.instance_variable_get(:#http).instance_variable_set(:#verify_mode, OpenSSL::SSL::VERIFY_NONE)
session = client.call('auth.login', params[:user], params[:pass])
sys_ver = session.call('api.systemVersion', session)
users = session.call("user.listUsers", session)
users.each { |uname| puts uname }
I've removed unnecessary arguments in the params hash and made sure everything is properly quoted.
It works and is only leaving me with a 404 error which is a problem with the script. But, at least it connects now and gives me something.
