TLS v1.3 Unsupported

[xunholy]

Using TLS v1.3 is unsupported in this project, it would be great if we could update the libs so this isn't an issue.

@xunholy I'll take a look at this as it should be easy to fix
.
Been a bit busy lately so trying to catch up on cases..

edit: Any chance you could try the latest build build (un-released). I think this should have been resolved by #166 (looks like I need to make a new release ...)
