I am new to Selenium and started learning it. But the Selenium Grid is not working for me. The server version used is selenium-server-standalone-3.14.0.jar. Using command, the hub and node are running.
The code for adding nodes to hub is written using TestNG in Eclipse. The code is as follows:

```
ChromeOptions options = new ChromeOptions();
options.setCapability(CapabilityType.PLATFORM_NAME, Platform.WIN10);             
options.setCapability(CapabilityType.BROWSER_NAME, "chrome");
driver = new RemoteWebDriver(new URL("http://192.xxx.x.xx:48807/wd/hub"), options);             driver.get("https://www.amazon.in/");

```

While running the test, the following error occurs and the sessions are not created:

```
