Authentication failure after upgrade to latest version, but CPE is on-boarded

Hi all, i upgrade our ACS from 1.2.3 to latest 1.2.8, now in the log file i can see a lot of Authentication failure, but if i look at the cpe i see that it’s onboarded and also i can change the parameters.
How can i fix it ?

In the debug file i’ve a lot of 401 error like this one:
