       Selector selector = Selector.open();
       SelectionKey connect_key =
         sock.socket().getChannel().register(selector, SelectionKey.OP_CONNECT);
-      // Try for the connection for 250ms
-      while (selector.select(250) > 0) {
+      // Try for the connection for 3000ms
+      while (selector.select(3000) > 0) {
         while (!result) {
 
           Set keys = selector.selectedKeys();
