It would help us to know if the 'arv-tool' CLI utility lists your camera.
cf. http://manpages.ubuntu.com/manpages/focal/en/man1/arv-tool-0.6.1.html
If it doesn't, I would suspect a network problem. Last I checked aravis
only did discovery by UDP broadcast, while some other clients have the
option for only UDP unicast. This was some years ago, so aravis might
be able to connect by IP address now.
Things to try. Check that both camera and computer have the same broadcast
address (and are on the same network segment). Check for firewall rules
effecting broadcasts.
fyi. Wireshark can decode some GVCP protocol messages.
