What NIC are you using for ethercat? Is the MAC address set correctly in this file?
Check the MAC Address with ip a
Your file mentions enp3s0 but thats not what you are using based on dmesg

Why is your address starting with 190???
The only local address ranges are 192.168.n.n and 10.n.n.n (there are two more that i do not recal as i rarely used them), these are non routable address ranges for use in local networks as they do not get routed to the internet, others can not be used unless you own a registered public IP address. And even then only the actual router can and should have that public address, not the local PC's.

you own a registered public IP address.

 you caught me, I'm doing other experiment other these where try to use these little pc with realtek port, so i need it .... having said this, it has nothing to do with the fact that enp3s0 is not working properly.... in fact that is enp1s0.
