I get the error "The proxy server is refusing connections" in eclipse - eclipse

Question

Hello I have tried to run the java code, but it gives the error "The proxy server is refusing connections"
Web page is not opened. I have checked the proxy setting as well. It is set as auto detect
still getting the error. I checked the firewall setting also. so please let me know what should do to solve the error
This is code:
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.MarionetteDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
//import org.openqa.selenium.firefox.FirefoxProfile;
import org.testng.Assert;
import org.testng.annotations.AfterTest;
//import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
public class sample_google
{
WebDriver driver;
#BeforeTest
public void setUp(){
// FirefoxProfile profile = new FirefoxProfile();
System.setProperty("webdriver.gecko.driver", "D:\\ashwini\\geckodriver.exe");
driver= new MarionetteDriver();
//driver = new HtmlUnitDriver();
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
#Test
public void testsample_google() throws Exception{
driver.get("https://www.google.com/");
// WebElement searchBox = driver.findElement(By.name("q"));
// searchBox.sendKeys("fast cars");
// searchBox.submit();
driver.findElement(By.name("q")).sendKeys("Selenium");
System.out.println("Page title : " + driver.getTitle());
WebElement resultCount = driver.findElement(By.id("resultStats"));
System.out.println("Result Count : " + resultCount.getText());
}
#AfterTest
public void teardown()
{
//driver.quit();
}
}
And error:
