MAC address not retrieved (after 2 years stop)

Hi.
After 2 years I went to my home made hobbystic cnc to realize a project.
When used last time, the machine worked perfectly.
But today, starting LinuxCNC, I got a message error then LinuxCNC quit.

Here you can find the message (only the Print File Information section):

As I can see, the problem should be the Mesa board MAC address.
I didn't make any change (configuration, setup or else) last time I used the system (2 years ago), so I don't understand what happens.
Honestly, I made a first try with ChatGPT (I know, not the best idea but at the moment maybe.... - moreover it looks to me AS - Artificial Stupidity - more than AI - Intelligence....), but its suggestions were totally useless (some changes to ini and hal files), so I resumed my original files (attached).

Currently, LinuxCNC keep quitting; LinuxCNC correctly connects to the MESA Board.

My OS is LinuxCNC 2.7.14 + MESA 7i76e (Hybrid stepper drivers)

Can anyone help me to fix it?

Thanks

Andrea

Whats does the command:

ip a

report?

What happens if you:

ping 10.10.10.10

?
