avahi-browse only find localhost, but no other network devices

When running avahi-browse -arvp

i only get results back from my own laptop, but nothing else
(i ran avahi-browse -arvp on my pi and i get all the network devices)

so i copied the /etc/avahi/avahi-daemon.conf from my pi to my laptop, restarted the avahi-daemon, but still only results form my own laptop…

i removed and reinstalled avahi, but still only results from my own laptop…

what am i missing here?
this used to work, but then for some reason, it stopped showing network connected devices…..
and honesty i have no idea where to start looking to fix this….
