I have scoured the web for information as well as the forums. There seems to be ways around this using .NET's intrinsic HTTP request classes, but the goal is to use the Unity API instead as work has been done to create these new Unity Web Request classes to replace the WWW class. It has been excruciatingly frustrating running into this. Does anyone (or perhaps someone from Unity) have a clear, working example of how to bypass expired / invalid certificates? Thanks.
