Arduino Leonardo ETH server problem

Hi, I recently bought Arduino Leonardo ETH board and tried to run example webserver code, but my board seems to freeze at server.begin(). I have spend whole day looking for solution and i found nothing. Im using arduino IDE 1.8.3, please help.

Are you using the Ethernet2 library? That device has a w5500 IC.

It worked! I feel so stupid now... Thank you!
