RMI Code works on PC but not on Android

[John]

I've written some code to utilize the RMI feature of KryoNet. I've followed the examples and it all worked great on my computer.

However when running the same code from within an Android application I get "com.esotericsoftware.kryonet.rmi.TimeoutException". Here's the full stacktrace:

com.esotericsoftware.kryonet.rmi.TimeoutException: Response timed out: xyz.test.lib.capabilities.IServerControl.getServerUptime

    at com.esotericsoftware.kryonet.rmi.ObjectSpace$RemoteInvocationHandler.invoke(ObjectSpace.java:408)

     at java.lang.reflect.Proxy.invoke(Proxy.java:393)

     at $Proxy0.getServerUptime(Unknown Source)

     at xyz.test.clientandroid.testClient.init(TestClient.java:70)

     at xyz.test.clientandroid.MainActivity$1.run(MainActivity.java:36)

What might be causing this?

I've changed the log level to STRACE and the conversation with the server looks as if everything worked out:
