I created a VM in the same network of the Raspi, with Debian Buster, too.
I installed a fresh sane on this VM and tried to detect the scanner.
I see in the syslog of the Raspi, that the VM is authorized (access
granted), I see with tcpdump on both devices data, but scanimage does
NOT detect any network scanner...
No Firewall between the devices, no network restriction, same version of
Curiously, I can see Broadbast packets sent from both the Raspi and the
VM, but the answer to these queries comes just from the network printers
in the network.

The network 192.168.5.0/24 is my network for printers. It has access to
my NTP-Server and my Mail-Server and my PC-Network (192.168.10.0/24) has
full access to the printer network.
With all printers and the old scanner (HP OfficeJet 6500a) it works...
