I fixed the issue myself , i was using a windows server dot net solution , and i just upgraded the dotnet frame work to 4.6.1, it support TLS 1.2 by default . Payeezy only support TLS 1.2 now and it will be updated to live urls from Feb 7 2018

according to them

So now it is got fixed

Some additional points , In sandbox only TLS 1.2 is supported. Any other protocols will cause a handshake failure or SSL error. If you have a .NET/C# integration you should be able to add a line of code to force TLS 1.2, update any system/web config files and additionally you may need to make an update in the Windows registry.
