Nightmare is a nightmare with proxies

[m0-n]

Hi -

my nightmare script works fine. Now I'm trying to have NightmareJS use some proxies.

This is how my code looks like:

const Nightmare = require('nightmare');

var nightmare = Nightmare({
    switches: {
        'proxy-server': 'exampleProxy.io:19081',
        'ignore-certificate-errors': true
    },
    show: true
});

nightmare
    .goto('http://www.example.com')

It sort of works, just incredibly slow, often with timeouts at 30000ms. I'm testing on a local machine. Without the proxy it's very fast. It can be seen as given that the proxy itself is working. Making a query to the proxy without nightmare / with curl it works just fine and at rapid speed.

Any idea what might be wrong?
