Getting Error: The request was aborted: Could not create SSL/TLS secure channel.

in Development
We have an integration in C# and it was working normally getting orders and transfers information, but it started failing for the error message on the SSL/TLS secure channel. WHo could help clarify what is going on to solve this?

I don't know a lot about C#, but I believe you need to either update .Net to a more recent version or set up your integration to use TLS 1.2.

If you upgrade to .NET 4.7.1 then TLS 1.2 should be enabled by default without doing anything. Otherwise in your C# code you can specify TLS 1.2 for any classes by including this line where your classes are instantiated or methods are called:
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
Hope this helps!
