node js won't let me use proxies - node.js

Question

I'm trying to use the request-module to scrape websites and get the response-HTML. To prevent getting blocked by the target sites I need to use some proxies. But for some reason I can not accomplish to use request with a proxy.
I've also tried many different proxies and none of them will do the job.
My code:
const request = require('request');
const cheerio = require('cheerio');
var servers = [
'http://173.249.48.240:8080',
'http://85.214.250.48:3128'
]
var options = {
'url': 'http://www.google.de',
'proxy': servers[1]
};
request(options, (err,res,body) => {
console.log(res);
console.log(body);
console.log(err);
try {
var $ = cheerio.load(body);
console.log($('#ipv4').html());
} catch(err) {
//do nothing
}
})
I've tried many different proxies and have also used nightmare before but everytime I try to connect with a Proxy I get the following exception:
{ Error: connect ECONNREFUSED 85.214.250.48:3128
at Object._errnoException (util.js:1024:11)
