TCP error code 10061: No connection could be made because the target machine actively refused it.

Question

I hosted a wcf service application using windows services. When my client (ASP.NET) tries to call the service class hosted by the windows service, I get this error "TCP error code 10061: No connection could be made because the target machine actively refused it. ". Is there a fix for this? The same code works fine if I host it using a console application.

Answer 1

What port are you listening on? Is that port unblocked in your windows firewall?

Answer 2

Yes, my firewall was blocking it. I got around it and it fixed the problem.

Answer 3

which port ?

Answer 4

Hi,

 

Evn i am gettin the same error. Can u tell me wat is the fix.

Answer 5

I am getting the same error - but only when I change my return type to a cutom object. CLR types work fine - i.e. an IList of Strings, but not, say, MyResponseObj. I'm running the asp.net development server on port 1212, with a wsHttpBinding. Like I said, the problem seems to be with the return type which is marked up with the DataContract - DataMember tags, like my other custom objects that work fine as input objects. I am able to pass in an arbitrarily complex object of custom types no problem - but the server tanks with a custom return type.

Any suggestion would be appreciated. Thanx - Ian

Answer 6

Regarding the custom-return-types problem, if you configure tracing

http://msdn2.microsoft.com/en-us/library/ms733025.aspx

are there any exceptions on the server?

I've configured trace in the web.config file as per the article, but no output or log file is generated. Do I need to create a trace object in my test code (NUnit) to explicitly start the trace segment?

Or should the web.config entry be sufficient?

 

Thanks,

Ian

Answer 8

Kenny,

 

I've unblocked the port on the firewall and still unable to connect.

What was the fix?

Answer 9

For problem returning custom objects, turns out my IList<T> member variable, since it could be nullable, required this in the data contract: [DataMember(EmitDefaultValue = false)]
That is what was causing the service to refuse the connection. Now all is well again.  A newbie error no doubt, but I never even heard of WCF before I started at my new company.  =o)

Answer 10

What port are you using? What binding is this? Can you connect to the port using IE (assuming you have an HTTP GET metadata enabled)?

Answer 11

Hi ,

 

I am getting this error if I host it using a console application. it works fine if client is asp.net. Is there a fix for this?

Answer 12

try to remove and add service refrences again...it will help you to connect wcf...

Answer 13

Hi JothiMurugan,

 

I am also getting same error when I host with the windows service.

Same application when hosted in Console application, works fine.

Can you please help me with the fix.

 

Thanks in advance.

Sakthi

Answer 14

hi
i don't know it will helpfull to u or not but u should try it
first u click on  host  project and  click on Start new instance
then u should run windows application

Answer 15

I have configured Tracing and I see my trace files just fine, the prblem is I don't see an Error icon. 

I'm looking through all the activities in the trace viewer and the one for my service operation has To and from transport messages, I can see the start for the activity but there is nothing indicating an error and I setup it up for  switchValue="Error,ActivityTracing".

Hi,
I am trying to write a WCF service with transport level security and basicHTTP binding. I am using a custom Membership provider to authenticate a client call to the service by authenticating the User ID and password passed to the service. I believe that WCF does not allow UserID/Password auth without having SSL certificate installed because the UserID/password are sent as clear text. I am currently in development and I tried installing the test certificate (X.509) on my dev machine running the service but w/o any success.
My service web.config looks like this

<

 

system.serviceModel>

<

 

services>

<

 

service behaviorConfiguration="LCCService.rbagLCWS_ServiceBehavior"

 

 

name="LCCService.rbagLCWS_Service">

</

</

 

binding>

</

 

basicHttpBinding>

</

 

bindings>

</

 

system.serviceModel>


When I try to call the service using the client w/o having the test certification installed, I get the following error:
Could not connect to https://XYZ.com/rrxainet/LCCWCFService/rbagLCWS_service.svc. TCP error code 10061: No connection could be made because the target machine actively refused it XXX.XXX.XX.XXX:443.

I have spent almost 2 days trying to figure out the solution and how to successfully install the test certificate to get it working but to no avail.

Please can someone help. I really appreciate it!!!

hi guys,

i am new to dot net. when i am using the folling program for connecting the particuler port it is giving the error.

int

 

timout = Convert.ToInt32(txttimeout.Text);

 

int port = 5000;

 

IPAddress localAddr = IPAddress.Parse("127.0.0.1");

 

IPEndPoint remoteEndPoint = new IPEndPoint(localAddr, port);

 

 

TcpClient NetworkClient = TimeOutSocket.Connect(remoteEndPoint, timout);

 

NetworkStream networkstream = NetworkClient.GetStream();

 

StreamReader streamReader = new StreamReader(networkstream);

 

string line = streamReader.ReadToEnd(); //streamReader.ReadLine();

Answer 18

I got the same message after adding the registry value  "KeepAliveTime" with value 300000 in the window registry under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters.

When I removed the window registry "KeepAliveTime", it resumed normal.

Is there any settings I have to check ?

Hi All,

 I am new to WCF. I have created a WCF Service and hosted it in Windows Service. I have got a below Error when tring to create Client Proxy for the service.

Error Message:

"There was an error downloading 'http://localhost:8051/Service1/'.

No connection could be made because the target machine actively refused it 127.0.0.1:8051
If the service is defined in the current solution, try building the solution and adding the service reference again."

I have seen some posts related to Issue like unblocking the port in Firewall. I have unblocked all ports from Firewall, Still the Issue raising while create Client Proxy. Some one can help me on this Problem. I have Pasted my configuration file below.

<system.serviceModel>

I started getting this problem in VS 2008 IDE when I'm testing my web services.  Not a firewall issue.  Anyone find a positive solution to this??

My Web Service test web application used to work fine a few months ago -- now when I test it I get this error?  So I'm guessing some OS update has broken VS 2008 IDE for web services??

Rob

Answer 21

Solved the problem for my case (appears to a Project's Web Service reference issue):

In VS 2008 IDE

In your actual Web Services Project (with the ASMX source) - My Project | Web | Use Visual Studio Development Server | Auto-assign Port.

a. If this is hard coded to a specific port you'll need to verify the calling Project's Web Service references match the same port and reference.

b. Open your calling project - My Project | References - remove your Web Service references (Type = Service) - be sure to note the ReferenceName you used.  Now Add Service Reference back again - Discover Services in Solution, select the service and be sure to re-enter the same ReferenceName you used originally.

If your Web Service project is configured differently or you reference external web services, then it might just be a case of removing and re-adding the web service back being sure to use the same ReferenceName so you project references stay intact.

Rob.

Answer 23

you have added your wcf reference by selecting wcf project node. to resolve it select your test project node and add wcf reference. i hope it will work.

Answer 25

Yeah! First time I ever fixed ANYTHING! Error went away when changed properties of project to use IIS instead of local directory.  Set the project to use IIS, click the button to create a virtual directory and...c'est voila!.  Good luck.

Answer 26

TrollSpouse, I seem to have this problem, but I don't understand the solution you found. Could you be more specific where in properties you configured  to use IIS instead of local directory? Thanks.

Answer 27

Make sure that "Net.Tcp Listener" is running go to  ControlPanel/Administrative Tools/Services
also "Net.Tcp Port Sharing"  Service.

Answer 28

My Net.tcp listener shows as starting, however starts... it shows the net.tcp Port Sharing as started, as well as the Windows Process Activation Service as started... i get the 10061 error as well... any idea how I can fix this?  would a service admin logon do it versus Local System/Service?
