problem is solved here: https://github.com/adafruit/Ethernet2/issues/32

nnn112358 commented on Sep 19, 2018 There is no problem with this.

If new arduino esp32 or make error, need go to c:\Program Files (x86)\Arduino\hardware\espressif\arduino-esp32\cores\esp32\Server.h Change virtual void begin(uint16_t port = 0) = 0; to virtual void begin() = 0;

For me the location of this file was in: C:\Users{your_user}\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.6\cores\esp32\Server.h

reopened arduino after opening the file and all was good, hope this helps mate :)
