[WebPlayer] [System.Net.Security.SslStream] SslStream.AuthenticateAsClient times out randomly

Networking

-

Reproduction steps:
1. Open attached project
2. Open scene "TestScene"
3. Enter play mode
4. Observe the console logs. If the request completes successfully, "Response received" will be printed. If it fails, indicating the bug has occurred, "Response failed" will be printed. Note, it takes exactly 5 minutes for the failure to occur. If the call does succeed, it typically takes a second or two. Therefore, if you find yourself waiting for more than 10 seconds, you can be reasonably certain the bug will occur.
5. If the bug does not occur, restart the editor and try again (it almost always does occur)

    There seems to be a difference in how often it occurs with different websites. I happened to make a test with https://dk.godaddy.com (our certificate provider) and with that, it happens every time.

    There is a small difference in how far it gets before it times out, but the exception is always "Mono.Security.Protocol.Tls.TlsException: Couldn't complete EndRead".

    Sometimes it gets to call the RemoteCertificateValidationCallback and sometimes it would even complete AuthenticateAsClient, only to fail with the same exception, when proceeding to read the stream.

    Do I need to make a repro project for you?

    Not so much randomly, as entirely predictably for us when running in the windows editor in 5.3.1f1: play in editor once, shutdown and play again and we hit this snag. Here's some callstack:

    This is incredibly important and needs to be addressed ASAP. There are a good number of us stuck on this one and requiring to roll our own native networking to support SSL.
