C# Selenium Chrome port issue?

Question

I am trying to use selenium with C# and chrome but it fails to connect.

My code:

string site = "https://google.de";
IWebDriver driver = new ChromeDriver(@"C:\test\");
driver.Navigate().GoToUrl(site);

Both, Chrome and the Chrome driver window are opening after a few seconds after the site has loaded and everything looks fine however, chrome driver is reporting the following:

Starting ChromeDriver 2.41.578737 (49da6702b16031c40d63e5618de03a32ff6c197e) on port 61455 Only local connections are allowed.

DevTools listening on ws://127.0.0.1:61458/devtools/browser/98bab62c-09d8-4714-b51b-4118ed7100c3 [1535800947.687][WARNING]: Timed out connecting to Chrome, retrying...

Is it possible that the application is using two different ports and this could lead to the timeout issue?

Answer 1

To fix this issue in the past I simply had to make sure both, Chrome and the Chrome driver were compatible and up-to-date, the best way to do this is to download the latest available versions which at the time of writing are:

• ChromeDriver 2.42
• Chrome 69.0.3497.100

The latest driver can be downloaded using NuGet: https://www.nuget.org/packages/Selenium.Chrome.WebDriver

Install-Package Selenium.Chrome.WebDriver -Version 2.42.0 

Or from the official site if you want to download it manually: https://sites.google.com/a/chromium.org/chromedriver/
