I tried taking a proxy from this site: /en/proxy-list/?type=4#list

Here is my Puppeteer scraping code (deployed to Heroku), which is returning the error in the title on the .goto() line:

const preparePageForTests = async (page) => {

const userAgent = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36';

  await page.setUserAgent(userAgent);

  await page.evaluateOnNewDocument(() => {
    Object.defineProperty(navigator, 'webdriver', {
      get: () => false,
    });
  });

  // Pass the Chrome Test.
  await page.evaluateOnNewDocument(() => {
    // We can mock this in as much depth as we need for the test.
    window.navigator.chrome = {
      app: {
        isInstalled: false,
      },
      webstore: {
        onInstallStageChanged: {},
        onDownloadProgress: {},
      },

          OS_UPDATE: 'os_update',
          PERIODIC: 'periodic',
        },
      }
    };
  });

  await page.evaluateOnNewDocument(() => {
    const originalQuery = window.navigator.permissions.query;
    return window.navigator.permissions.query = (parameters) => (
      parameters.name === 'notifications' ?
        Promise.resolve({ state: Notification.permission }) :
        originalQuery(parameters)
    );
  });

  await page.evaluateOnNewDocument(() => {
    // Overwrite the `plugins` property to use a custom getter.
    Object.defineProperty(navigator, 'plugins', {
      // This just needs to have `length > 0` for the current test,
      // but we could mock the plugins too if necessary.
      get: () => [1, 2, 3, 4, 5],
    });
  });

  await page.evaluateOnNewDocument(() => {
    // Overwrite the `plugins` property to use a custom getter.
    Object.defineProperty(navigator, 'languages', {
      get: () => ['en-US', 'en'],
    });
  });
}

const browser = await puppeteerExtra.launch({ headless: true, args: [                
'--no-sandbox', '--disable-setuid-sandbox', '--proxy-server=socks4://109.94.182.128:4145']});

const page = await browser.newPage();

await preparePageForTests(page);

await page.goto('+near+new+york&client=safari&rls=en&uact=5&ibp=htl;events&rciv=evn&sa=X&fpstate=tldetail#htivrt=events&htidocid=L2F1dGhvcml0eS9ob3Jpem9uL2NsdXN0ZXJlZF9ldmVudC8yMDIxLTA2LTA0fDIxMjMzMzg4NTU2Nzc1NDk%3D&fpstate=tldetail') 

I also sometimes get an "ERR_CONNECTION_CLOSED" or "ERR_CONNECTION_FAILED" instead of ERR_CONNECTION_RESET.

Any help in getting rid of this error (presumably by adding more ways to pass the google tests in the preparePageForTests function) would be amazing, thank you!

• In my case this is happening randomly using a local nodejs server with puppeteer. – Neil Gaetano Lindberg Commented Jun 2, 2021 at 14:32
• 1 @NeilGuyLindberg Not sure why that is, and I'm still not sure how to fix mine which isn't a local server... – nickcoding2 Commented Jun 2, 2021 at 20:46

You're using low-quality public proxies and it's only natural that they will generate network errors and/or be blocked by Google. The simplest solution here is to go for paid ones.

But it's also possible to intercept the error and repeat request if page.open failed:

const collectData = async (page) => {
  try {
    await page.goto('https://www.google.com/search?q=concerts+near+new+york');
    return page.evaluate(() => document.title);
  } catch (err) {
    console.error(err.message);
    return false;
  }
}

let data = false;
let attempts = 0;

// Retry request until it gets data or tries 5 times
while(data === false && attempts < 5)
{
  data = await collectData(page);
  attempts += 1;  
  if (data === false) {
    // Wait a few seconds, also a good idea to swap proxy here*
    await new Promise((resolve) => setTimeout(resolve, 3000));
  }
}

---

* Modules for changing proxies programmatically:

• https://www.npmjs.com/package/puppeteer-page-proxy
• https://www.npmjs.com/package/proxy-chain

You need to await the page.goto("...")

await page.goto("https://google.com", {waitUntil: "networkidle2"});
