title: Puppeteer not chaning my IP
body: <p>Basically, any proxy server (for example from this website <a href="https://www.socks-proxy.net/" rel="nofollow noreferrer">https://www.socks-proxy.net/</a>) will not change my IP</p>
  
  <pre><code>const puppeteer = require('puppeteer');
  
  (async () =&gt; {
    const browser = await puppeteer.launch({
      args: ['--proxy-server=http=188.134.1.20:63756'],
      ignoreHTTPSErrors: true,
      headless: true
    })
    const page = await browser.newPage()
    await page.goto('https://www.purevpn.com/what-is-my-ip', { waitUntil: 'networkidle0' })
    // I can see my native IP on a screenshot
    await page.screenshot({ path: 'example.png' })
  
    await browser.close()
  })()
  </code></pre>
  
  <p>What am I missing?</p>
