i think you have built your project on .net framework < 4.5.2. so, above 4.5.2 framework by default supports TLS1.2 and lower version will not support.

to do this, you need to build your project with above 4.5.1 framework or need to add below statement to over come TLS1.2 issue

System.Net.ServicePointManager.SecurityProtocol = Net.SecurityProtocolType.Tls12;

Hope this will help you to resolve your issue.

Thanks!
