In the other topic that you’ve been posting in, I suggested that you come back here and…
You’ve provided some info on your hardware, but I still have no idea which Ethernet board you are actually using.
Also, you should be testing this with a bare minimum sketch, and providing info on exactly which libraries and library versions you are using.
All of this is to allow others to replicate your setup and see if they can get this setup working.
