APs with Dawn do not see each other

Hi !
I setup 2 of my 3 APs with Dawn (actual release / after doing all with 802.11r/k/v) just to test how its working etc.
I installed all packaged with "dawn" inside (were 3) and setup the broadcast address.
In network overview i see only the local AP and not the other one...
only thing i can see that during startup i have this in my log
Mon Mar 27 11:08:19 2023 daemon.warn dawn: Failed to lookup ID!
Any way to check what is wrong ?

Ciao Gerd
