Chrome Headless in Unix returns empty page source

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)    

It's problem with ssl certificate , i also had the same issue . for headless chrome following options are not effective , try to reach other non ssl link . chrome options - > --ignore-ssl-errors
