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

Hi, 

I trying to call soap API by custom .Net Script in designer and I hit the exception as The request was aborted: Could not create SSL/TLS secure channel

I've put the solution from online such as add  

ServicePointManager.SecurityProtocol = CType(3072, SecurityProtocolType)

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls Or SecurityProtocolType.Tls11 Or SecurityProtocolType.Tls12

but didn't work.

Anyone have similar experience before?

My one identity manager version is 8.0, .net version is 4.0.
