Selenium grid is not working for a rookie example

Question

I can't get Selenium grid working. I've included screen shots below to help. Can anyone see what's wrong? I've almost given up, looking at tutorials/ articles/ videos out there what I've tried below should work but it doesn't. Can anyone advise? Thanks

Update

Watch the problem in this short youtube video https://www.youtube.com/watch?v=zhWhhDnR1Bg

Server jar file location

Command to start the selenium server

After starting the server

Question update

An exception of type 'OpenQA.Selenium.WebDriverException' occurred in WebDriver.dll but was not handled in user code

Additional information: Unexpected error. System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: The requested address is not valid in its context 0.0.0.0:4444

New Console application

Executing this new code after starting the selenium hub and node throws an exception:

static void Main(string[] args)
{
    var url = new Uri("http://10.6.122.49:4444/wd/hub");

    var driver = new RemoteWebDriver(url, new FirefoxOptions());  // This line throws an exception

    driver.Navigate().GoToUrl("http://www.google.com");

 }

Have tried the following although the error still happens

Environment.SetEnvironmentVariable("webdriver.gecko.driver", @"D:\geckodriver.exe");

After trying the curl command

$ curl -i -H "Accept: application/json" -X POST -d '{"desiredCapabilities":{"bro % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0HT Date: Fri, 29 Sep 2017 15:27:00 GMT Expires: Thu, 01 Jan 1970 00:00:00 GMT Cache-Control: no-cache Content-Type: application/json;charset=utf-8 Server: Jetty(9.4.3.v20170317) Content-Length: 5374

Answer 1

The error The requested address is not valid in its context is indicating that the IP address is perhaps invalid. I found that from The requested address is not valid in its context when i try to listen a port

In your command prompt wherein you started the hub, you would notice a line like this Nodes should register to http://10.6.122.49:4444.

In your tests you can try instantiating a RemoteWebDriver with the IP 10.6.122.49 instead of localhost.

And I am hoping that you have started the node and had it register itself to the hub.

On some machines (especially in the MAC) I have noticed that at times localhost doesn't work and you would need to add your machine name as well to the /etc/hosts file [ This may or may not be applicable to your issue ]

I would also suggest that you take a look at this Tutorial (or book, you can call it whatever you want) that I created, which helps you get oriented with the Grid and its setup apart from a lot of other things which you would like to know about the Grid. See here
