chat app SSLSocket SSLHandshakeException

Question

Hey i'm building a chat application, I was previously using regular sockets for communications but want to add encryption so I've switched over to SSL sockets. However since switching to SSL sockets as soon as I go to send a message I receive a SSLHandshakeException, can anyone give me any clues as to why this is happening? Below is the ServerConnection class:

import javax.net.ssl.SSLServerSocket
import javax.net.ssl.SSLServerSocketFactory
import java.net.Socket
import java.net.ServerSocket
import java.io._
import scala.io._


class ServerConnection(port: Int) {

  def connect(): Socket = { 
    val factory = SSLServerSocketFactory.getDefault()
    val serverSocket = factory.createServerSocket(port)
    serverSocket.accept() 
  }  

  def getMsg(client: Socket): String = new BufferedSource(client.getInputStream()).getLines().next()

  def sendMsg(client: Socket, msg: String): Unit = {
    val out = new PrintStream(client.getOutputStream())
    out.println(msg)
    out.flush()
  }

  def close(client: Socket): Unit = client.close() 

Below is the ClientConnection class:

import javax.net.ssl.SSLSocket
import javax.net.ssl.SSLSocketFactory
import javax.net.SocketFactory
import java.net.Socket
import java.net.InetAddress
import java.net.InetSocketAddress
import java.io._
import scala.io._
import java.util.Calendar

class ClientConnection(host: InetAddress, port: Int) {

 def connect(): Socket = { 
   val sslfactory = SSLSocketFactory.getDefault()
   val sslsocket = sslfactory.createSocket(host, port)
   sslsocket
  }

 def getMsg(server: Socket): String = new BufferedSource(server.getInputStream()).getLines().next()

 def sendMsg(server: Socket, user: User, msg: String): Unit = {
   val out = new PrintStream(server.getOutputStream())
   out.println(this.getCurrDate() + " " + user.getUsername() + ": " + msg)
   out.flush()
 }  

 def getCurrDate(): String = "(" + Calendar.getInstance().getTime().toString().substring(11, 19) + ")"

 def close(server: Socket): Unit = server.close()
}

EDIT: Below is the full stack trace
