Selenium gives error while launching

[kuba11g]

Hey I got question,

When I'm starting app Selenium gives me error like this

OpenQA.Selenium.WebDriverException: 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 127.0.0.1:55628 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception) --- End of inner exception stack trace --- at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context) at System.Net.HttpWebRequest.GetRequestStream() at OpenQA.Selenium.Remote.HttpCommandExecutor.MakeHttpRequest(HttpRequestInfo requestInfo) at OpenQA.Selenium.Remote.HttpCommandExecutor.Execute(Command commandToExecute) at OpenQA.Selenium.Remote.DriverServiceCommandExecutor.Execute(Command commandToExecute) at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters) at OpenQA.Selenium.Remote.RemoteWebDriver.UnpackAndThrowOnError(Response errorResponse) at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters) at OpenQA.Selenium.Remote.RemoteWebDriver.set_Url(String value) at OpenQA.Selenium.Remote.RemoteNavigator.GoToUrl(String url) at InstagramBotz.InstagramPanel.FollowUserFollowers(String userUrl, Int32 amount, Int32 time)

Could someone help me to fix this error? I will appreciate it.

There could either be a firewall blocking the connection or the process that is hosting the service is not listening on that port. This could be possible if it is not running at all or because it is listening on a different port. When you begin the process, try netstat -anb (requires admin privileges) to verify that it is running and listening on the expected port. You can get better insights from the selenium testing training.

It will be because your Internet service provider might be blocking your access to the port. Kindly contact your internet service provider and ask them about the same and unblock from their end so that you can go ahead with your connection request. Once you are done with contacting your ISP, restart your selenium software. Visit for more - Selenium testing training.

Try to clear the cookies and caches
