    }

}

------------------------------Invoking Browser Below --------------------------

public WebDriver standAloneStepUp(BrowserType bType) throws Exception {
        WebDriver driver;
        
        try {
            oLog.info(bType);

            switch (bType) {

            case CHROME:
                //ChromeBrowser chrome = ChromeBrowser.class.newInstance();
                //WebDriverManager.chromedriver().setup();
                System. setProperty("webdriver.chrome.driver", System.getProperty("user.dir")+"\\src\\main\\resources\\driver\\chromedriver.exe");
                driver = new ChromeDriver();
                return driver;

            case FIREFOX:
//              FirefoxBrowser firefox = FirefoxBrowser.class.newInstance();
//              WebDriverManager.firefoxdriver().setup();
                System. setProperty("webdriver.gecko.driver", System.getProperty("user.dir")+"\\src\\main\\resources\\driver\\geckodriver.exe");
                driver = new FirefoxDriver();
                //driver = new FirefoxDriver(firefox.getFirefoxOptions());
                return driver;


         default:
                throw new NoSutiableDriverFoundException(" Driver Not Found : " + ObjectRepo.reader.getBrowser());
            }
        } catch (Exception e) {
            oLog.equals(e);
            throw e;
        }
    }

Solution

I figure it out what was the issue. Actually this happens when you are accessing the site which is not yet open to public. So got it resolved in two steps :

• First I connected to client VPN
• Though connected to client VPN but still I was getting this same issue so went and added few lines related to clinet url along with ip address in host file

Path of host file : C:\Windows\System32\drivers\etc\host
