I'm using the WCF4.0 template -REST. I'm trying to make a method that uploads a file using a stream.
The problem always occur at
Stream serverStream = request.GetRequestStream();
Class for streaming:
namespace LogicClass
{
public class StreamClass : IStreamClass
{
public bool UploadFile(string filename, Stream fileStream)
{
try
{
FileStream fileToupload = new FileStream(filename, FileMode.Create);
byte[] bytearray = new byte[10000];
int bytesRead, totalBytesRead = 0;
do
{
bytesRead = fileStream.Read(bytearray, 0, bytearray.Length);
totalBytesRead += bytesRead;
} while (bytesRead > 0);
fileToupload.Write(bytearray, 0, bytearray.Length);
fileToupload.Close();
fileToupload.Dispose();
}
catch (Exception ex) { throw new Exception(ex.Message); }
return true;
}
}
}
REST project:
[WebInvoke(UriTemplate = "AddStream/{filename}", Method = "POST", BodyStyle = WebMessageBodyStyle.Bare)]
public bool AddStream(string filename, System.IO.Stream fileStream)
{
LogicClass.FileComponent rest = new LogicClass.FileComponent();
return rest.AddStream(filename, fileStream);
}
Windows Form project: for testing
private void button24_Click(object sender, EventArgs e)
{
byte[] fileStream;
using (FileStream fs = new FileStream("E:\\stream.txt", FileMode.Open, FileAccess.Read, FileShare.Read))
{
fileStream = new byte[fs.Length];
fs.Read(fileStream, 0, (int)fs.Length);
fs.Close();
fs.Dispose();
}
string baseAddress = "http://localhost:3446/File/AddStream/stream.txt";
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(baseAddress);
request.Method = "POST";
request.ContentType = "text/plain";
Stream serverStream = request.GetRequestStream();
serverStream.Write(fileStream, 0, fileStream.Length);
serverStream.Close();
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
int statusCode = (int)response.StatusCode;
StreamReader reader = new StreamReader(response.GetResponseStream());
}
}
I've turned off the firewall and my Internet connection, but the error still exists. Is there a better way of testing the uploading method?

"Actively refused it" means that the host sent a reset instead of an ack when you tried to connect. It is therefore not a problem in your code. Either there is a firewall blocking the connection or the process that is hosting the service is not listening on that port. This may be because it is not running at all or because it is listening on a different port.
Once you start the process hosting your service, try netstat -anb (requires admin privileges) to verify that it is running and listening on the expected port.
update: On Linux you may need to do netstat -anp instead.
You don't have to restart the PC. Restart IIS instead.
Run -> 'cmd'(as admin) and type "iisreset"
You must set up your system proxy
You have to go through this path

I got a similar error message like TCP error code 10061: No connection could be made because the target machine actively refused it in my current project. I find this 10061 error code cannot distinguish the case that the service endpoint is not started and the case that it is blocked by the firewall. Often, the firewall can be switched off, but the problem is still there.
You can test your code in the below two ways.
Insert code to get time A that service is started and time B that client sends the request to the server. If B is earlier than A, it can cause this problem.
Change your server port to another port that is also available in the system. You will find the same error code reported.
Above is my fix. It works on my machine. I hope it helps!
Check if any other program is using that port.
If an instance of the same program is still active, kill that process.
I had a similar issue. In my case the service would work fine on the developer machine but fail when on a QA machine. It turned out that on the QA machine the application wasn't being run as an administrator and didn't have permission to register the endpoint:
HTTP could not register URL http://+:12345/Foo.svc/]. Your process does
not have access rights to this namespace (see
http://go.microsoft.com/fwlink/?LinkId=70353 for details).
Refer here for how to get it working without being an admin user: https://stackoverflow.com/a/885765/38258
If you use WCF storm, can you even log-in to the WCF service endpoint? If not, and you are hosting it in a Windows service, you probably forgot to register that namespace. It's not very well advertised that this step is required, and it is actually annoying to do.
I use this tool to do this; it automates all those cumbersome steps.
Check whether the port number in file Web.config of your webpage is the same as the one that is hosted on IIS.
I had the same problem on my web server "No connection could be made because the target machine actively refused it 161.x.x.235:5672". I asked the Admin to open the port 5672 on the web server, then it worked fine.
I had a similar problem
rejecting localhost and 127.0.0.1.
cmd(admin) netstat -anb found the port running on 169.254.80.80 (dont know were that ip came from because my network ip was 10.0.0.5.
after putting in this IP it worked.
This Gives correct IP:
IPAddress ipAddress = ipHostInfo.AddressList[0];
Console.WriteLine(ipAddress.ToString());
I also faced problem in .Net Remoting Service in C#.
I got it solved in 3 steps:
Change Port of Protocol in all the files whereever it is being used.
Run your Host Server Program and make it active.
Now run your client program.
I could not restart IIexpress. This is the solution that worked for me
Cleaned the build
Rebuild
With this error I was able to trace it, thanks to #Yaur, you need to basically check the service (WCF) if it's running and also check the outbound and inbound TCP properties on your advance firewall settings.
With similar pattern, my rest client is calling the service API, the service called successfully when debugging, but not working on the published code. Error was: Unable to connect to the remote server.
Inner Exception: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it serviceIP:443 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)
Resolution: Set the proxy in Web config.
<system.net>
<defaultProxy useDefaultCredentials="true">
<proxy proxyaddress="http://proxy_ip:portno/" usesystemdefault="True"/>
</defaultProxy>

I had a similar issue. In my case VPN proxy app such as Psiphon ، changed the proxy setup in windows so follow this :
in Windows 10, search change proxy settings and turn of use proxy server in the manual proxy
Make Sure all services used by your application are on, which are using host and port to utilize them . For e.g, as in my case, This error can come, If your application is utilizing a Redis server and it is not being able to connect to it on given port and host, thus producing this error .
For my case, I had an Angular SLA project template with ASP.NET Core.
I was trying to run the IIS Express from the Visual Studio WebUI solution, triggering the "Actively refused it" error.
The problem, in this case, wasn't connected with the Firewall blocking the connection.
It turned out that I had to run the Angular server independently of the Kestrel run because the Server was expecting the UI to run on a specific port but wasn't actually.
For more information, check the official Microsoft documentation.
I had similar problem. In launchSettings, my IIS Express was configured on one port, and there was another launch profile that started on another ApplicationUrl with another port.
Starting the web app up with the IIS Express profile led me to have the error.
I am using the Apache ActiveMQ Artemis AMQP message broker. I started getting the "No connection could be made because the target machine actively refused it" exception when trying to send and receive messages with the broker after a reboot. On a computer where the same type of broker still worked, netstat -anb showed that the broker was listening on the expected port 5672. On the computer with the error, the broker was not listening. On the computer with the error, starting the broker resulted in the following warning's appearing in Microsoft Event Viewer's "Windows Logs > System":
The system failed to register host (A or AAAA) resource records for network adapter
with settings:
Adapter Name : {286EE2DA-3D81-41AE-VE5G-5D761FD3925E}
Host Name : mypc
Primary Domain Suffix : myco.com
DNS server list :
55.77.168.1, 74.86.130.1
Sent update to server : 186.952.335.157:45
IP Address(es) :

Either the DNS server does not support the DNS dynamic update protocol or the authoritative zone for the specified DNS domain name does not accept dynamic updates.
To register the DNS host (A or AAAA) resource records using the specific DNS domain name and IP addresses for this adapter, contact your DNS server or network systems administrator.
I was able to use the broker without error after I ran the following in a cmd.exe with administrative privileges, rebooted, and waited about fifteen minutes:
ipconfig /flushdns
ipconfig /renew
ipconfig /registerdns
I am making an Android Application using GCM. I am trying to register through my app running on phone, the inputs are not able to store on localhost XAMPP using php. My phone and laptop are running on the same network. There is some problem with the ip address of localhost. I am using this url for saving on local host, where 192.168.43.247 is the ip address when pc is running with the help of phone's 3G network.
192.168.43.247/gcm_server_php/register.php
Please help!
Open Xampp>apache>conf>http-conf file in notepad.
Find Listen 80 and comment out using #(like #Listen 80) and write below it: Listen (static ip address of server):80
eg:
Listen 192.168.1.34:80
If you want to use your application on emulator with localhost database(Xampp) then you have to use the IP address 10.0.2.2 instead of other local ip address .. if you want to use your aap on mobile then you you can use same ip .. press up arrow on left side if my answer is usefull for you
try to check by disabling firewall or use ipconfig /all command then get your ip from there and use this ip as server ip address.
If still facing error then it might be error of your local server the request may be block or something else that you need to find out.to check it try to open url in your android mobile browser.
In my Android application, I wanna be able to access the wamp server files via the PC name (hostname) not PC local IP address, Is it that possible? cause the user need to change the local IP address in Android app. each time needs to update or get data from MySQL database which annoying thing!
// url to get all items list
private static String url_all_items="http://Local IP Address/android_connect/test.php";
But what I need to be able to send PC name not local IP address as:
// URL to get all items list
private static String url_all_items="http://PC Name/android_connect/test.php";
Actually, I tried to send the PC name instead of Local IP address but this does not work, I tried many solutions, In wamp server configurations, on hosts on windows file, etc. BUT also this not work! Is there any additional configurations to be able to send PC name via the android app instead off IP address?! although when I send local IP address it works well!
In sum, Is there any way that I can access the WAMP server using the PC name instead of the local IP address?
any help at all would be greatly appreciated.
The simple way to solve your problem is without doing any configuration in the wamp server or in the windows, however the solution lies in the code itself. As I see, you don't want the android app user to put or use IP, you just allow the user to put the sever name only. Thus, the best way to do that is by getting the IP address of the entered server name. On the IP address of server name is obtained, you can rebuild the needed URLs using the returned IP. The following code shows a piece of code that helps you in the implementation.
private static String url_all_items="http://%s/android_connect/test.php";
private static void ResolveURL() {
try {
InetAddress addr = InetAddress.getByName("mahdi-pc");
String host = addr.getHostAddress();
url_all_items=String.format(url_all_items, host);
System.out.println(url_all_items);
} catch (UnknownHostException ex) {
}
}
Using the above code, it is clear that the sever name in this case is named "mahdi-pc" and the returned IP address will be for it. Note that this code is valid only for local network addresses. After that, the returned IP address is replaced in url_all_items link using string format. Once the link is formatted correctly , you can establish your connection with using the IP address without using the name of the server in the URL.
I hope that the solution works fine with you.
i have created a new Facebook application and i used the following url as canvas url http://localhost/my_app/
my code works perfectly on localhost, but when i try to cal my application using the following url : apps.facebook.com/leenaaps its displays the following error:
Unable to connect
Firefox can't establish a connection to the server at localhost
what could be the problem exactly?
You most likely do not have a local webserver running. If you do, it might be possible that Facebook uses https:// but you did not configure/enable SSL.
localhost is resolved to ip 127.0.0.1 and this is the local loopback address whcih means it is not routable and cannot be accessed from the internet, So you cannot use it in your canvas url.
You have to use a valid and active domain name like domain.com. If you don't have a public web server you may use some DDNS service, google it some are free
