Google login is not working in headless chrome selenium in Jenkins job

Solved google login issue by adding --user-agent flag with headless chrome.

--user-agent="Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.102 Safari/537.36"

Chrome headless browser won't necessarily have the same screen size set as the normal Chrome (I think it is 800 x 600, but I'm not sure).

Try adding the following options:

chromeOptions.addArguments("--start-maximized");chromeOptions.addArguments("--window-size=1200,800");

Obviously, set the screen size you want in the place of 1200x800.

I used to have the same problem, in headless used other google login page. I resolved it this way:

driver.get("https://accounts.google.com/signin/v2/identifier");    WebElement emailField = driver.findElement(By.id("Email"));    emailField.sendKeys(login);    WebElement loginNext = driver.findElement(By.id("next"));    loginNext.click();    logger.info("Enter password");    WebElement passwordField = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("Passwd")));    passwordField.sendKeys(password);    WebElement passwordNext = driver.findElement(By.id("signIn"));    passwordNext.click();
