Within seconds after discovering my amps they all go offline. I can still add them to the workspace but the link state is inactive. This is true of Armonia 2.3.1 and 2.4.0. Amps are all M series. Normal setup is through a switch on a dedicated network. I get the same result going direct to the amp and bypassing the switch and I have swapped out the ethernet cable. I need to manage presets on a repaired amp and cannot do so if I can't talk to it.
we need you to answer some question to better understand the problem:
are your amplifier in auto or static ip?
...and your pc?
have you checked the "communication manager"? (armonia menu, in the top-left corner -> options -> communication manager)
try to pause/play the network from there.
can you successfully connect to just a single amplifier, straight from the pc?
