Amp Controller "Authentication passthru is disabled on the controller"

OS Name/Version: Ubuntu X 3 (2 V22.04 and 1 V21.10)

Problem Description: Authentication passthru is disabled on the controller


I have a problem with the controller who refuses to modify one of the targets.
I’ve already tried a reset of the parameters but it doesn’t change anything.
I do not encounter this problem with the second target which is a local PC/Test Server which I control without any problem from the controller despite the regular shutdowns of it.

If you have solutions, thank you.
