RemoteWebDriver throws = SessionNotCreatedException : Unable to create session from org.openqa.selenium.remote.NewSessionPayload#57ab6ec1

I'm trying to run a test using Opera browser as a node, hub and node connections are succesful.
Below is for hub and node connections:
Hub > java -jar selenium-server-standalone-3.9.1.jar -role hub
Node > java -Dwebdriver.opera.driver=C:\zip\exe\operadriver_win64\operadriver_win64\operadriver.exe -jar selenium-server-standalone-3.9.1.jar -role node -hub http://192.168.1.10:4444/grid/register -port 5566
When trying to executing the program two Opera browser loads but only blank white pages shown with Not secure data:; on URL and I am also getting this kind of exception.

The RemoteWebDriver url configuration should always be routed to the hub, if using the Selenium Grid setup as your browser stack. The hub will then check for a node which matches your browser request and forward onto that node.
nodeUrl = "http://<hub ip address>:4444/wd/hub";
DesiredCapabilities capabilities = DesiredCapabilities.opera();
capabilities.setBrowserName("opera");
capabilities.setPlatform(Platform.WINDOWS);
driver = new RemoteWebDriver(new URL(nodeUrl), capabilities);

Unable to initialise using #FindBy in selenium webdriver java

I am trying to perform basic selenium operations using page object pattern. However, when I run the test, I see browser being opened along with given url, but fails the test by complaining it couldn't initialise the declared web element. Can some one please help me to understand what I'm missing here. Below are my base class, page object class and test class.
BasePage
public class Basepage {
public static WebDriver driver;
public Basepage(){}
public Basepage(WebDriver driver){
this.driver = driver;
PageFactory.initElements(driver,this);
}
public void OpenBrowser(){
System.setProperty("webdriver.chrome.driver",
"C:\\SeleniumWork\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
driver.navigate().to("https://www.google.com");
}
Page object class
public class SecurityMainPage extends Basepage{
public SecurityMainPage(WebDriver driver){
this.driver = driver;
PageFactory.initElements(driver,this);
}
#FindBy( xpath = "//a[text()='What We Do']")
WebElement dropdown;
public void selectOption(String option){
Actions actions = new Actions(driver);
actions.moveToElement(dropdown).click().build().perform(); //dropdown element is returning null
}
TestClass
public class SecurityMainPageTests extends Basepage {
protected static SecurityMainPage sec = new SecurityMainPage(driver);
public SecurityMainPageTests(){}
#BeforeTest
public void setup(){
OpenBrowser();
}
#Test
public void selectOptionTest(){
sec.selectOption("Networking");
}
#AfterTest
public void tearDown(){
closeBrowser();
}

For easy understanding, I split the driver initiation and navigation to url to two methods in Basepage. And you haven't declared the closeBrowser() method.
Base Class
public class Basepage {
public static WebDriver driver;
public Basepage(){}
public Basepage(WebDriver driver){
this.driver = driver;
PageFactory.initElements(driver,this);
}
public WebDriver initiateDriver(){
System.setProperty("webdriver.chrome.driver",
"C:\\SeleniumWork\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
return driver;
}
public void openBrowser(String url){
driver.navigate().to(url);
}
}
Test Class
public class SecurityMainPageTests extends Basepage {
WebDriver driver = null;
protected static SecurityMainPage sec = null;
String url = "https://www.google.com";
public SecurityMainPageTests(){}
#BeforeTest
public void setup(){
driver = initiateDriver();
openBrowser(String url);
sec = new SecurityMainPage(driver);
}
#Test
public void selectOptionTest(){
sec.selectOption("Networking");
}
#AfterTest
public void tearDown(){
closeBrowser();
}
}

Could any one Explain why I am getting this error and how it can be fixed

That's because you change page in your test, thus your element references break. Have a look at WebDriverExtensions. This framework provides method on opening your links in new windows without invalidating references of WebElements, and enables dynamic lookup of your elements.
Alternatively, if you don't want to use this framework, you could re-search for your elements in your loop like this:
//...
for (int j = 0; j < sheet.getColumns() - 1; j++) {
// add these lines
emailTextBox = driver.findElement(By.xpath("//input[#id='email']"));

All test Fails automatically after first #Test failure from same class

I use TestNG + Selenium + Appium.
Problem which i have is:
If the 1st #Test fails, all rest got failed automatically and execution will be stopped.
I tried to use #BecoreClass setUp instead of setting up at #Test still after first failure fails everything.
I thought that it skipping all the rest of the test because of it does not finish the process in the right way ( quitting an application ) that`s why i added #Aftermethod with driver.quit that it will execute it after failed method.
But still after 1st failure it automatically Fails all the tests.
I need to have multiple #Test with a test methods, which will be individual with separate configurations. And if 1st one fails, it will continue execute the rest of #Test ( even if they are from the same class) and after will give me a result .

Move driver = DesiredCapabilitiesSetup.startAppiumServer... to #BeforeMethod. Also if you want to use different drivers for tests you will have to add parametrization (e.g. #BeforeMethod for group, #DataProvider or #Facotry).

Selenium Webdriver HtmlUnitDriver: UnreachableBrowserException

I am randomly getting an org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died. error, i.e., it doesn't always happen with the same input in the same code. The code:
public class PortalListingCallable implements Callable<Listing> {
private WebDriver driver;
private WebElement event;
public PortalListingCallable(WebElement event) {
driver = new HtmlUnitDriver();
this.event = event;
}
public Listing call() {
//System.out.println("in PortalLisingCallable");
Listing newListing = ListingFactory.createListing(
new PortalScheduleEventsEvent(driver, event.findElements(By.tagName("td"))).parse());
driver.close();
return newListing;
}
}
I have also tried the line Listing newListing = ListingFactory.createListing(new PortalScheduleEventsEvent(new HtmlUnitDriver(), event.findElements(By.tagName("td"))).parse());
This class implements Callable, so it's being called by multiple threads, but the data is independent. That code:
while (webElementsQueue.peek() != null) {
Callable<Listing> callable = new
PortalListingCallable(webElementsQueue.poll());
//Future<Listing> future = executor.submit(callable);
Future<Listing> future = executor.submit(new Callable<Listing>() {
#Override
public Listing call() throws Exception {
try {
return callable.call();
} catch (Exception e) {
e.printStackTrace();
throw e;
}
}
});
listingQueue.offer(future);
}
I suspect that this has something to do with this being called in multiple threads, but since each instance of HtmlUnitDriver is isolated, I'm not sure how.
Below is the exception:
org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died.
