try the WebClient example of the Ethernet library (comment out lines with compilation errors)

No, I don't have such a server, but my concern is in getting an address from DHCP server. I don't understand why NodeMCU does not get the address.

BTW, if I reset NodeMCU it gets the address and it works. :o What could cause such a behaviour?

Powering of what? NodeMCU or enc28j60? Right now NodeMCU is powered by my workstation's USB-port via USB-interface. enc28j60 is powered from 3v3 of NodeMCU.

the NodeMcu 5 V to 3.3 V regulator then must feed both power hungry chips. if the enc28j60 module has a 5 V VCC, then use that
