Puppeteer automation stuck in endless Cloudflare human verification loop

I’m having trouble with Puppeteer and Cloudflare’s human verification. My script keeps getting stuck in an endless loop, even when I try to solve the captcha manually or use bypass extensions.

I’ve tried different browsers, user agents, and headers, but nothing seems to work. I’m using puppeteer-extra and the stealth plugin. Here’s a simplified version of my code:

const puppeteerExtra = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');

puppeteerExtra.use(StealthPlugin());

async function runBrowser() {
  const browser = await puppeteerExtra.launch({
    headless: false,
    args: ['--proxy-server=proxy.example.com:8080'],
  });

  const page = await browser.newPage();
  await page.setUserAgent('Mozilla/5.0 ...');
  await page.setExtraHTTPHeaders({ 'Accept-Language': 'en-US,en;q=0.9' });

  await page.authenticate({ username: 'user', password: 'pass' });

  await page.goto('https://example.com/login', { waitUntil: 'networkidle2', timeout: 0 });

  await page.type('#email', '[email protected]');
  await page.type('#password', 'password123');
  await page.click('#login-button');

  await page.screenshot({ path: 'result.png' });
}

runBrowser();

The script gets stuck on the Cloudflare page, looping endlessly. Any ideas on how to fix this?

I’ve dealt with similar Cloudflare issues in my automation projects. One thing that’s worked well for me is using 2captcha or a similar service to solve the CAPTCHAs automatically. It’s not free, but it’s saved me a ton of headaches.

Another trick is to warm up your browser session gradually. Start by visiting some popular sites, clicking around, and maybe even logging into a social media account before hitting your target site. This can make your traffic look more natural.

Also, don’t underestimate the power of timing. I’ve found that adding random delays between actions and varying the speed of typing can make a big difference. Cloudflare’s algorithms are pretty sophisticated, so mimicking human behavior as closely as possible is key.

Lastly, if you’re still having trouble, you might want to look into using undetected-chromedriver. It’s designed specifically to bypass these kinds of detection mechanisms.

yo, i’ve been there. cloudflare’s a real pain. have u tried using a residential proxy instead? sometimes datacenter IPs get flagged. also, try adding some random delays between actions. might help fool the bot detection. good luck man!

I’ve encountered similar issues with Cloudflare. One approach that’s worked for me is implementing a custom Cloudflare challenge solver. This involves detecting the presence of the challenge page and executing specific JavaScript to bypass it. Additionally, consider rotating your IP addresses frequently and incorporating realistic mouse movements and keystrokes into your script. These techniques can help mimic human behavior more closely. Remember, Cloudflare continually updates its detection methods, so staying current with anti-detection strategies is crucial for maintaining long-term success in your automation efforts.
