I try to call a remote REST Web API. My tests in Postman are successful. but in .Net Framework 4.5.2 and using a HttpClient I get this error:
The request was aborted. Could not create SSL/TLS secure channel.
As mentioned Here, I set the followings:
System.Net.ServicePointManager.Expect100Continue = true;
System.Net.ServicePointManager.SecurityPortocol = System.Net.SecurityProtocolType.Tls12;
Also, I tried this one
but nothing has changed.
thanks for any help in advanced!
