Running firefox Selenium driver on Hosting Server c#

Question

I published my automation project and send to host server. When I try to reach it from web first I got this error on page ;

 FireFox executable listed in the registry does not exist, please make sure you have installed FireFox correctly

after a few search I find this and add my code

 DesiredCapabilities capability = DesiredCapabilities.Firefox();
 capability.SetCapability("platform", Platform.CurrentPlatform);
 capability.SetCapability("binary", "C:\\Program Files (x86)\\Mozilla Firefox\\msfirefox.exe");            
 IWebDriver driver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), capability);

now I am getting this error on page ;

Unexpected error. System.Net.WebException: Unable to connect to the remote server --->                   System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:4444

I am a bit confused here, can't I run it in server or not ?

Answer 1

The issue is probably the URL you are trying to hit. http://localhost:4444/wd/hub refers to the current machine's 4444 port, that means if you access that page on your developer machine, it hits your developer machine. If you access it on the server, it hits the server. Do you have /wd/hub running on the server?
