selenium server Unable to connect to the remote

I am trying to start remote driver in selenium using the following code
at the server side
DesiredCapabilities capability = DesiredCapabilities.Chrome();
Uri url = new Uri("http://www.globalcontactcentre.org:99/wd/hub");
IWebDriver site = new RemoteWebDriver(url, capability);
and started selenium server using the following string :
java -jar F:\sawy\driver\selenium-server-standalone-3.5.0.jar -port 99
and I have allowed connections through port 99 in the fire wall
but I still got this error client side
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 MY-IP:99

--- End of inner exception stack trace ---

and even I tried to but the code in try catch statement

unable to know what is blocking to my application to communicate to Web service

Recently we were facing an issue in client place is that we were unable to communicate to web service even we checked that there is no system proxy set in that system, to overcome this we had given a dummy proxy (localhost:port) and its started working well but after some days with dummy proxy it was unable to communicate to service if we remove dummy proxy then it started working well. i am not able to understand what is blocking me to communicate to service. what may be the issue and how can we overcome this problem. This issue is happening only on some system.
Actually it has to go and hit this URL http://********-tech.in:8080/******dp/ClientVersion but suddenly it started hitting this one 125.21.244.38:8080 why i am not able to conclude.

Please read this post here they are telling to set the default proxy for the webservice request, they are trying to the proxy details while connecting to google. If there is no proxy configured you can try the method mentioned there. Set the default proxy.

Unable to access api via Azure website

I am using HttpClient to make the request.
Below is the original stack error:
System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 209.99.17.14:443 at System.Net.Sockets.Socket.EndConnect(IAsyncResult asyncResult) 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.EndGetResponse(IAsyncResult asyncResult) at System.Net.Http.HttpClientHandler.GetResponseCallback(IAsyncResult ar)Reqes
The same code works in local dev environment.

Cannot initialize AndroidDriver

At W2k8 64 bit I have in the android emulator instance of android 4.1 API Level 16 with ARM as CPU.
After launch of it I'm running my UnitTest and on the first line
var webDriver = new AndroidDriver("http://localhost:8080/wd/hub"); //also with no argument
I got an exception:

Version of this WebDriver is 2.25.1.0.
I followed this article:
http://www.nishantverma.com/2011/06/installing-webdriver-on-android.html
When I'm using other drivers like Firefox- or ChromeDriver works fine.
I would be gratefull for any advice

I might be telling you what you already know, but have you started the tcp port forwarding to android server you are running. for reference check Android Driver

Your server is not starting for some reason. Is it possible you already have something else running on port 8080?
Try running netstat -a -n and see if port 8080 is listed.
If it is in use, you might try setting up on a different port or killing the process which is using that port.
You might also try disabling UAC and Firewall on your machine and/or running the process as Administrator and see if that helps (This would be temporary of course, don't leave these off).

Webservice SocketException - Only Breaks On One Application

I have a few applications which use a single Web Service which resides on the same server as the applications.
Why would only one of the applications have a problem connecting to a web service? And is there a way I can better diagnose exactly what the problem is with the connection?
It won't even connect to a web service the application itself is hosting
I have tried running it from my local machine and it works fine (updated the web ref url and the connection string to point to the liver server), which should rule out that the code itself is the problem.
I have tried setting up a different virtual directory to point to the application; and later copying the entrie app to another location on the same server and setting it up there. No luck.

Found it... the proxy was the cause of the issue and it is the only application where I specify proxy different from the default:
Since I only need the proxy locally I disabled it on the live web.config with enabled="false"
<defaultProxy enabled="false">
<proxy
autoDetect="False"
bypassonlocal="True"
scriptLocation="http://www.proxy.something"
proxyaddress="http://proxy.com" />
</defaultProxy>
