title: Selenium Grid: URL in RemoteWebDriver(url, caps)
body: <p>I am trying to run a test suite using selenium grid, and I was able to establish hub and one node. After this, when I am initializing the RemoteWebdiver(url, caps) call, it is throwing an exception:</p>
  
  <pre><code>org.openqa.selenium.WebDriverException: Error forwarding the new session Error forwarding the request Failed to connect to &lt;IP&gt;:&lt;PORT&gt;
  </code></pre>
  
  <p>Also when I ping to that "Node_IP", it shows 100% loss. But my grid console shows it is connected. I have added inbound and outbound rules for the port: 4444 through firewall. telnet command also fails for "Node_IP" and "PORT" which is "4444". </p>
  
  <p>I can execute the tests in my local when I pass the URL as : <a href="http://localhost:4444/wd/hub" rel="nofollow noreferrer">http://localhost:4444/wd/hub</a></p>
  
  <p>/**** Added Description *****/<br>
  <strong>hubConfig</strong>: java -jar selenium-server-standalone-3.13.0.jar -role hub -host "Host_IP"<br>
  <strong>nodeConfig</strong>: java -Dwebdriver.chrome.driver="chrome_driver_location_on_node" -jar selenium-server-standalone-3.13.0.jar -role node -hub http://"host_ip":4444/grid/register -browser 
  "browserName=chrome,platform=WINDOWS,version=67.0,maxInstances=5"</p>
  
  <p>Same goes for FireFox and IE.<br>
  Code works fine as I am able to execute as a localhost.  </p>
  
  <p><strong>The stacktrace is as:</strong><br>
  FYI: "Node_PORT" is a random port. I have not assigned it. I also tried it by assigning a port but it didn't work too.</p>
