Failure to Authenticate

[amenpatron]

Have an older website that cant be upgraded due to older third party custom controls. The server was configured approximately a year ago to use TLS1.2 and all older versions where disabled.

This is the soap call being used to initiate the connection. It initiates acall and immediately closes.

[System.Web.Services.Protocols.SoapDocumentMethodAttribute("https://api.authorize.net/soap/v1/ARBCancelSubscription", RequestNamespace="https://api.authorize.net/soap/v1/", ResponseNamespace="https://api.authorize.net/soap/v1/", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]

        public ARBCancelSubscriptionResponseType ARBCancelSubscription(MerchantAuthenticationType merchantAuthentication, long subscriptionId) {

            object[] results = this.Invoke("ARBCancelSubscription", new object[] {

                        merchantAuthentication,

                        subscriptionId});

            return ((ARBCancelSubscriptionResponseType)(results[0]));

        }

Remove your dependency on 3rd party controls. The application is very likely to be using deprecated endpoints and methods.

Third party controls make up 60 percent of the site. It would be easier to switch merchants

You should check with the following, to ensure your server actually was configured properly:

using System;
using System.Net;
using System.IO;

namespace howsMySSL
{
    public partial class Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
            var response = WebRequest.Create("https://www.howsmyssl.com/a/check").GetResponse();
            var responseData = new StreamReader(response.GetResponseStream()).ReadToEnd();
            Response.Write(responseData);

        }
    }
}
