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 must set up your system proxy
You have to go through this path
controlpanel>>internet option>>connnection>>LAN settings>>
proxy
no tik:use proxy server
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!

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.

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());
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.
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>
</system.net>
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
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) :
182.269.1.437
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
You are browsing to 127.0.0.1, which is localhost, or the local machine. When doing this in Windows results in a 401, it may be worth investigating the loopback check registry setting.
Disclaimer: Editing the registry is potentially dangerous if you don't know what you're doing.
First, browse to this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
Under Lsa
, add a new DWORD
value called DisableLoopbackCheck
, with a value of 1
. Then try your request again. If that works, you've found a workaround/solution. However, this setting should not be used in production because it's a security risk. A somewhat better solution would be to revert that change and go to this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
Under MSV1_0
, create a new Multi-String
value called BackConnectionHostNames
, with a value that includes the application host name(s) that you want to exclude from the loopback check. Example:
This is recommended over DisableLoopbackCheck
because we can disable the check for only the host(s) we need, so it should be more secure, in theory. However, it still leaves the system vulnerable for the specified host names, so only proceed with this solution if the level of risk is acceptable in your situation.
