discoverHost throws error on iOS

Using client.discoverHost on Android and desktop works without issue. But it fails on iOS (using for RoboVM for port). (For information creating a server on iOS works perfectly, you can connect to it with an Android Client and all goes well. )

The stack:

[WARN] java.lang.Class: Class.forName() failed to load 'android.os.Process'
Exception in thread "Thread-7" java.lang.IllegalArgumentException: sockaddrToInetAddress bad ss_family: 0
