[Mobile] Getting TlsException: Handshake failed - error code when trying to connect to a host

Mobile

-

To reproduce:
1. Open user attached project "TestWebSocket.zip"
2. Open "SampleScene.unity" scene
3. Enter Play mode
4. Observe in the console "SSL Stream complete"
5. Build for iOS
6. Deploy the Xcode project to an iOS device
7. Observe in the top UI "TlsException: Handshake failed - error code: UNITYTLS_INTERNAL_ERROR, verify result: UNITYTLS_X509VERIFY_FLAG_NOT_TRUSTED"

Expected result: getting the same result on the device as in the Editor console "SSL Stream complete"
Actual result: getting "TlsException: Handshake failed - error code: UNITYTLS_INTERNAL_ERROR, verify result: UNITYTLS_X509VERIFY_FLAG_NOT_TRUSTED" error

Reproduced on:
2018.3.0f1 2018.3.14f1 2019.1.0a1 2019.1.7f1 2019.2.0b7 2019.3.0a6

Device reproduced on:
- iPhone 8 Plus iOS 12.0
- VLNQA00009, Samsung Galaxy Note8 (SM-N950F), Android 8.0.0, CPU: Exynos 9 Octa 8895, GPU: Mali-G71

Notes:
- Getting another issue on 2018.3.0b12 and earlier because of this: https://fogbugz.unity3d.com/f/cases/1134343/

  1. Resolution Note (2018.4.X):

    The certificate used by this server uses a key with incorrect usage flag, which should be easy to fix by creating a new certificate using a key with the right usage settings. MbedTLS which we use on most platforms (but not on Desktop/editor) rejects the entire handshake if this usage flag is incorrectly set.
