You are absolutely can’t connect with the machine No.: 11:= DTMD3 because the machine No. 11 is stand for IP: 10.2.10.11 which it doesn’t has anymore.
If I’m not wrong, the machine that you can connect is the machine No.: 9:= DTMD1 (10.2.10.222; changed from 10.2.10.11) and machine No.: 10:= DTMD2 (10.2.10.221).
So that’s why Eagle as you to connect the old machine with contain IP: 10.2.10.222 then Eagle will remote to change this machine to IP: 10.2.10.11 for your spare part. Thank you.
