ios Crash SetStatusCode()

Hello,

We're using Untiy3d 5.4.1 and the latest Xcode 8. Our application uses internet connection to fetch some data from our server. But even if we totally shut down our network part, we receive crash while application in idle (active but without any activity)

In xcode we got next stack-trace:

Please see attached full stack trace.link text

Any ideas what cause it ? Seems like it is internal Untiy3d call.

Thank you.
