Selenium Webdriver Communication Error

Question

I'm doing a java project which uses selenium web driver to automatically do tasks in a website, but getting errors.

Set System.setProperty("webdriver.chrome.driver","path to chrome driver");

Have this method

public boolean openBrowserAndLoadUrl(String url) {          
        ChromeOptions options = new ChromeOptions();
        options.addArguments("--disable-extensions","--start-maximized");
        WebDriver driver = new ChromeDriver(options);
        if(driver==null)
            return false;
        driver.get("https://www.google.co.in");
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        return true;
}

pom.xml

<org.seleniumhq-version>2.53.1</org.seleniumhq-version>

<!-- Selenium -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-chrome-driver</artifactId>
        <version>${org.seleniumhq-version}</version>
    </dependency>
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>htmlunit-driver</artifactId>
        <version>2.23</version>
    </dependency>

The 'driver' variable is initialized and Google Chrome is opened. Eclipse debugging shows exception occurs here driver.get("https://www.google.co.in");

Got two types of error in two times!. Both stacktrace are shown below.

org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died.

Later i got this error

On further research, i understand many had this issue, but I didn't get any solution except incompatible version issue. But i am using downloaded chromedriver.exe

Also, earlier all the selenium steps had succeeded with this chrome driver and same selenium version.. Don't know why this happened now! Please help.

Google Chrome installed in your windows system may have been updated automatically.
You can download the latest driver from the chrome driver website.
