Selenium Chrome WebDriver Cannot start Driver service on port

Question

I am not able start ChromeWebDriver/IE/Firefox and it throws me a error message

This issue occurs only with

• Selenium C# Binding with ChromeDriver
• Occurs when I am connected to my Organization's VPN

Doesn't occur with Python ChromeDriver binding

OpenQA.Selenium.WebDriverException:Cannot start the Driver Service on http://localhost:59343

Answer 1

It could be the case that a process of the WebDriver is still running in the background. Fire up Task Manager to see and end it if does.

Answer 2

I had the same problem, when I used Selenium.Webdriver 3.00-beta1 with Firefox in Visual Studio. After update to version 3.00-beta2 it start work good.
