Error in opening new driver window:
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
server log:
Forwarding newSession on session null to remote
I am running following code on linux:
driver= new RemoteWebDriver((new URL( "http://"+ip+":5555/wd/hub")), capability);
My hub-node already up and running. Then why i am getting this error.
This error message...
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
and the server log...
Forwarding newSession on session null to remote
...implies that the Selenium Grid Hub / Selenium Grid Node wasn't properly initiated/started. As a result a null session was forwarded to the RemoteWebDriver.
Some more information regarding the versions of the binaries which you have used interms of Selenium server/client, WebDriver variant /version and WebBrowser variant /version and the commands you have used to initiate the Selenium Grid Hub / Selenium Grid Node would have helped us to debug your issue in a easier way.
However this issue can happen due to multiple factors as follows:
5555/wd/hub, so ensure that Selenium Grid Hub is initiated on port 5555.You may opt to replace the capability argument with an instance of Options class as follows:
DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability("browser", "chrome");
//seting the required capabilities
ChromeOptions options = new ChromeOptions();
options.merge(caps);
WebDriver driver = new RemoteWebDriver((new URL( "http://"+ip+":5555/wd/hub")), options);
