problem connecting Controllino MEGA with WizNet5100

[bluelemonade]

hello, I changed the hello world demo to my local settings and added the W5100 definition.

#define W5100
#include "SocketIOClient.h"
#include "Ethernet.h"
#include "SPI.h"

SocketIOClient client;

byte mac[] = { 0xAA, 0x00, 0xBE, 0xEF, 0xFE, 0xEE };
char hostname[] = "192.168.1.56";
int port = 9021;

the Controllino coundn't connect to the node socket server. I tried a socket.io only, on http and on express server. nothing! no firewall.

any ideas?
