Puppeteer not loading page - NodeJs - node.js

Question

Here is a simple program on puppeteer:
const puppeteer = require('puppeteer');
async function run() {
const browser = await puppeteer.launch({
headless: false,
args:[ `--proxy-server=104.233.50.38:3199`]
});
;
const page = await browser.newPage();
await page.authenticate({
username: 'myusername',
password: 'mypassword'
})
await page.goto('https://google.com')
};
run();
Note: I have tried similar with over 10 proxies and none of them are working in puppeteer
The credentials are exactly what is provided to me, I have checked multiple times.
This is what I get:
Now again , this is the console of the page:
Why is this happening?
I checked the addresses and username, password multiple times. There is no other error message except this.

Answer 1

It seems that page.authenticate is not working for me either,instead you can use page.setExtraHTTPHeaders
async function run() {
const browser = await puppeteer.launch({
ignoreHTTPSErrors: true,
args: ['--proxy-server=104.233.50.38:3199']
});
const page = await browser.newPage();
await page.setExtraHTTPHeaders
({'Proxy-Authorization': 'Basic ' + Buffer.from('username:password').toString('base64'),
});
};
run();

You can use puppeteer-page-proxy, it offers username and password auth very easily. It also supports http, https, socks4 and socks5 proxies. https://github.com/Cuadrix/puppeteer-page-proxy
You can define the proxy this way:
const proxy = 'http://login:pass#IP:Port';
or
const proxy = 'socks5://IP:Port';
Then you can use it per request:
const useProxy = require('puppeteer-page-proxy');
await page.setRequestInterception(true);
page.on('request', req => {
useProxy(req, proxy);
});
