org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session error with Selenium and IE11 using Java

I'm trying to automate my test cases using Selenium with the following software applications.

Here's my script to initialize the driver.

System.setProperty("webdriver.ie.driver","driver path");
driver = new InternetExplorerDriver();
System.out.println("Driver initialized.");
driver.get("application web url");

For the above script, I'm getting the below error message.

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session....

I have tried with different versions of drivers and selenium webdriver. But didn't workout. What could be the cause and how can I resolve it?

Could anyone give me your suggestions?

Thanks,

  • This error message...

    org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session....

    ...implies that the IEDriverServer was unable to initiate/spawn a new WebBrowsing Session i.e. InternetExplorer Browser session.

    Your main issue is the incompatibility between the version of the binaries you are using as follows:

    So there is a clear mismatch between Selenium Client v3.12.0 , IEDriverServer v3.150.1.
