Nano Every with ENC28j60 Ethernet Shield

I have a Nano with the Ethernet example Webserver and the EthernetENC library running. Now I change the Nano with the Nano Every, because of more memory and nothing works. What could be the reason?

Could it be something to do with the code, the schematic, the error messages or explanation of what "works" means, you didn't post?

use Ethernet.init(10); to set the CS pin

Thank you very much, thats it.
