okhttp: Crash: Unexpected TLS version: NONE

Hi there!

First at all thank you very much for your library!

I’ve integrated okhttp3 since couple months ago; there were no problem until yesterday with an user (Huawei, model MHA-L29, on Android 7.0):

Have you got some ideas about this crash?

Thank you very much guys!

Also, that stack trace appears to be 3.8.
