Am using Chrome Headless to run my selenium test script in Unix machine(Cent OS).But the same script works perfectly in my local windows machine.
But in Unix machine it returns empty page source like empty html tags.
Have no clue where its error-ed out though am using latest ChromeDriver 2.33, and google chrome version 62.0..
System.setProperty("webdriver.chrome.driver", "/../chromedriver.exe");
--chromedriver.exe for windows local machine
-- chromedriver for unix machine
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
options.setAcceptInsecureCerts(true);
options.addArguments("--ignore-ssl-errors=true");
options.addArguments("--ssl-protocol=any");
options.setHeadless(true);
driver = new ChromeDriver(options);
System.out.println("Timeout invoke ");
driver.get("https://www.google.co.in/");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
System.out.println("After invoke ");
System.out.println("PAGE SOURCE : \n" + driver.getPageSource());
System.out.println("RUN COMPLETE..");
Running the above in Unix machine i get
PAGE SOURCE:
<html xmlns="http://www.w3.org/1999/xhtml"><head></head><body></body></html>
Help me in fixing this Thanks in advance

You can run Google Chrome in headless mode simply by setting the headless property of the chromeOptions object to True. Or, you can use the add_argument() method of the chromeOptions object to add the –headless command-line argument to run Google Chrome in headless mode using the Selenium Chrome web driver.
As we have already seen, you just have to add the flag –headless when you launch the browser to be in headless mode. With CLI (Command Line Interface), just write: chrome \<br> – headless \ # Runs Chrome in headless mode. <br> – disable-gpu \ # Temporarily needed if running on Windows.
Headless Chrome is a way to run the Chrome browser in a headless environment without the full browser UI. One of the benefits of using Headless Chrome (as opposed to testing directly in Node) is that your JavaScript tests will be executed in the same environment as users of your site.
Headless Chromium allows running Chromium in a headless/server environment. Expected use cases include loading web pages, extracting metadata (e.g., the DOM) and generating bitmaps from page contents -- using all the modern web platform features provided by Chromium and Blink.
To run Chrome Browser in Headless Mode in Unix Systems, add the arguments --disable-gpu and --remote-debugging-port=9222 :
System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
options.setAcceptInsecureCerts(true);
options.addArguments("--ignore-ssl-errors=true");
options.addArguments("--ssl-protocol=any");
options.setHeadless(true);
options.addArguments("--remote-debugging-port=9222");
options.addArguments("window-size=1400,600");
WebDriver driver = new ChromeDriver(options);
System.out.println("Timeout invoke ");
driver.get("https://www.google.co.in/");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
System.out.println("After invoke ");
System.out.println("PAGE SOURCE : \n" + driver.getPageSource());
System.out.println("RUN COMPLETE..");
Note A: Avoid passing both the options addArguments("--headless") and setHeadless(true) together for any single WebDriver instance.
Note B: Avoid using addArguments("--disable-gpu"); on Linux/Unix based systems as it is a configuration for Windows based OS.

I had the same issue. Especially when adding the proxy which had no valid certificates. Here's what worked for me: (python code)
polipo_proxy = "127.0.0.1:8124"
proxy = Proxy({
'proxyType': ProxyType.MANUAL,
'httpProxy': polipo_proxy,
'ftpProxy' : polipo_proxy,
'sslProxy' : polipo_proxy,
'noProxy' : ''
})
capabilities = dict(DesiredCapabilities.CHROME)
proxy.add_to_capabilities(capabilities)
capabilities['acceptSslCerts'] = True
capabilities['acceptInsecureCerts'] = True
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--ignore-certificate-errors')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--window-size=1280,1000')
chrome_options.add_argument('--allow-insecure-localhost')
chrome_options.add_argument('--allow-running-insecure-content')
chrome_options.add_argument('--no-sandbox')
driver = webdriver.Chrome(executable_path=os.path.abspath("/var/chromedriver/chromedriver"), chrome_options=chrome_options, desired_capabilities=capabilities)
