Unable to connect to selenium grid node

I am trying to connect to a no on a Linux machine with the RemoteWebDriver, but have been unsuccessful. This is the code:

public WebDriver googlechrome(){ /*Method to start Google Chrome.*/

    WebDriver driver = null;
    ChromeOptions options = new ChromeOptions(); /*ChromeOptions is for firing Chrome with additional settings.*/
    options.addArguments("--allow-file-access-from-files"); /*Allow Chrome to access files*/
    options.addArguments("user-data-dir="+System.getProperty("user.dir")+pathChrome);
    DesiredCapabilities capabilities = DesiredCapabilities.chrome();
    capabilities.setCapability(ChromeOptions.CAPABILITY, options);
    capabilities.setBrowserName("chrome");
    capabilities.setPlatform(Platform.LINUX);
    try { //            driver = new RemoteWebDriver(new URL("http://localhost:9515"), capabilities);
         driver = new RemoteWebDriver(new URL("http://jenkins.bgr.ionidea.com:4444/grid/console"),capabilities);
         Chatterbox.chatterinfo("Connected to Chromedriver");
    } catch (Exception e) {
        Chatterbox.chattererror("Could not connect to Chromedriver. Here is the stacktrace:", e); //           
        e.printStackTrace();
    }
    return driver;
}

When I run this code on the local machine, it works fine. However, when I try to run it via Grid, the following error is encountered.

org.openqa.selenium.WebDriverException: Unable to parse remote response: Grid Console.busy { opacity : 0.4;filter: alpha(opacity=40);}

The first line of the exception says that it is unable to parse something, but I can't understand what?

Am I missing something? I am doing grid setup for the first time.

Solution

The problem lies in the below line

driver = new RemoteWebDriver(new URL("http://jenkins.bgr.ionidea.com:4444/grid/console"),capabilities);

You are connecting to the Console servlet instead of connecting to the servlet that's responsible for honoring new sessions.

Please change the above line to

driver = new RemoteWebDriver(new URL("http://jenkins.bgr.ionidea.com:4444/wd/hub"),capabilities);

and try again. You should be fine.
