Still not fixed in 2019.1.6f1 (occurs when using System.Net's ClientWebSocket to establish a secure connection).

In the same situation as NILSUBIMAX, except trying with NET 4.x API compatibility level. Does not work in Unity 2018.2.9f1, and also not in 2018.3.0b3. IL2CPP build targeting UWP platform. We are using a self-signed certificate, but we load the cert into the certificate store prior to trying to open any socket connection.

I am also getting the UNITYTLS_X509VERIFY_FLAG_NOT_TRUSTED result with 2018.3.0b4. I'm using System.Net.ClientWebSocket with a self-signed certificate. My code is working within a WPF application, but the same .NET Standard 2.0 library fails within Unity (editor as well as HoloLens (IL2CPP project).

Getting a slightly different exception now: "TlsException: Handshake failed - error code: UNITYTLS_INTERNAL_ERROR, verify result: UNITYTLS_X509VERIFY_FLAG_NOT_TRUSTED". The domain I am connection to verifies fine in all web-browsers.
