An existing connection was forcibly closed by the remote host

[ Edited ]

Hello.

 

I'm trying to fix my test requests. For now when I'm sending a request to the 'https://apitest.authorize.net/xml/v1/request.api' I'm getting an exception.

 

[SocketException (0x2746): An existing connection was forcibly closed by the remote host]

 TLS 1.2 is enabled, Windows Server 2008 r2. Any suggestions please?

 

Thanks!

Re: An existing connection was forcibly closed by the remote host

Try adding the following to your application in order to see what version of TLS your schannel.dll is using:

var response = WebRequest.Create("https://www.howsmyssl.com/a/check").GetResponse();
var responseData = new StreamReader(response.GetResponseStream()).ReadToEnd();
Response.WriteLine(responseData);

If < TLS 1.2 add the following at the beginning of the function where you make a webrequest:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

Re: An existing connection was forcibly closed by the remote host

 Thank you @NexusSoftware!

 

Now I'm getting "

The client and server cannot communicate, because they do not possess a common algorithm

" error.

 

I think the reason is that I have a website running on ASP.NET 2,0 & .Net 2.0 so I should upgrade them too ASAP.

Re: An existing connection was forcibly closed by the remote host

Yes, .Net version 4.6 supports TLS 1.2 by default. Version 4.5 can be set to use TLS 1.2 using the above mentioned  technique.

Configuration Details of my local machine

 

I am testing the Authorise.NET API with Sample Code Solution downloaded from GIT repository in Visual Studio 2012. I have installed .NET framework 4.6.2 on my Windows.

 

Target .NET version I have set in config files is as follows

 

App.config

<startup>

       <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.2" />

</startup>

 

Packages.config

 

<packages>

<package id="AuthorizeNet" version="1.9.3" targetFramework="net462" />

</packages>

 

I can't even explictly set  to TLS12 in my code as it does not  show me tLS2 option

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls

 

Would appreciate your support on resolving this issue.

 

Thanks

Sesha

Hello, 

using System.Net;
using System.Security.Authentication;

  In the function where you make your web request, try: 

   const SslProtocols _Tls12 = (SslProtocols)0x00000C00;
   const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;
   ServicePointManager.SecurityProtocol = Tls12;
