TLS 1.2 not working on Windows server 2008 standard machine

[smandola]

I have setup TLS1.2 on windows7 machine where I installed 4.6 framework and made .net code changes under 4.0 and it started working there but when I did same changes on windows server 2008 server then I am getting same error. I am using Asp.net code and framework as 4.0. Please help as my Production is down.

Once you're sure your server's Schannel is using TLS 1.2, upgrade your server application to .NET 4.5 or 4.6. If you're not using a newer version of the SDK, be sure to use the following before your application's webRequest:

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