Setting Port on chromedriver.exe

[SeleniumIntern]

I was getting the following error when using the chrome driver in C#

: OpenQA.Selenium.WebDriverException: No response from server for url http://localhost:62289/session/e0b6b5d1a3a2f68165dc7e56eaabb745/elements

After doing some online searches most say its too many connections to a proxy server? (not using a proxy) or a firewall block.

I emailed my network helpdesk seeing if they could open a port for me to try if that will work.  But I will need chromedriver.exe to always use the same port if I do that.  I tried the following code

Enter code here...            ChromeOptions chromeOptions = new ChromeOptions();
            chromeOptions.AddArgument("port=8080");      
            chromeDriver = new ChromeDriver(@"D:\SVN\CSP\Trunk");

but it didn't change the port, (also tried '--port = 8080')

If you have any ideas on how to fix the error I am getting or how to set the port to a static number I would appreciate the help.  Thanks!

Have you tried using what selenium uses as default, which is 4444. Try that and see what happens.

I dont think port 4444 is applicable in the case of ChromeDriver or any other driver for that matter.

I believe it is applicable only when you instantiate DefaultSelenium.

Thanks & Regards

I am having trouble getting the syntax/process right to actually set the port.  Once I can get it to set the port I can try the different options.

You can't in the .NET bindings. At least, not yet. There is a pending change that will allow you to explicitly set the port for the chromedriver.exe. In the meantime, you can manually launch chromedriver.exe with the specific port and use the RemoteWebDriver class.

I set up the 'remote' driver, tried port 8080, 39, 4444, they all still gave me the "No response from server for url " once I got to uploading a CSV file, I guess now I have to wait for my helpdesk to open up something unless my thoughts on what is wrong are incorrect?

If you managed to set the port, I would appreciate to hear a solution. I tried a lot of different ways but none works. I need the correct syntax. Thx!

start the chrome driver like this: (in .Net )   

string DRIVER_PATH = ConfigurationManager.AppSettings[“ChromeDriverPath”];
ChromeDriverService serviceCR = ChromeDriverService.CreateDefaultService(DRIVER_PATH);
serviceCR.Port = 9510;
IWebDriver WebDriver = new ChromeDriver(serviceCR);

Hi Mohammad,

How to set port for chromedriver using java. My selenium test cases are getting failed beacuse of firewall blocking default port.
