Routing Remote Actors: Peer not authenticated - scala

Question

I am I am trying to route remote actors following this example:
http://doc.akka.io/docs/akka/snapshot/scala/routing.html#Remotely_Deploying_Routees
Here is the code:
val system = ActorSystem("RemoteSystem", ConfigFactory.load.getConfig("remotecreation"))
val addresses = Seq(AddressFromURIString("akka://ActorApplication#172.17.100.224:2552"),
AddressFromURIString("akka://ActorApplication#172.17.100.232:2552"))
val worker = system.actorOf(Props[authNetActor.AuthNetActorMain].withRouter(RemoteRouterConfig(RoundRobinRouter(5), addresses)))
However I am getting an error saying that one of the server ip addresses is not authenticated.
Here is the error (this is from: 172.17.100.224:2552):
[ERROR] [09/20/2012 18:13:02.192] [ActorApplication-akka.actor.default-dispatcher-11 [akka://ActorApplication/remote/RemoteSystem#172.17.100.231:2554/user/$a/c1] peer not authenticated

The error occurs only for this server and the difference between them are that the code path is different and they create actor systems on their own local ip addresses. Otherwise the code for these two actor systems are the same.
I'm not sure exactly how to fix this error or why it is thrown for just one server.
Any help is appreciated, thanks.

It seems an SSL handshaking exception.
Maybe the involved server have not a valid SSL certificate, or you have not registered the untrusted certificate in the client keystore.
