Can't connect to a USB spectrometer using pyseabreeze on machine with no IP

[tpwrules]

On my Linux machine the following program fails if it has no IP (i.e. WiFi off, Ethernet unplugged) (it is replicatable on several machines):

import seabreeze
seabreeze.use("pyseabreeze")
import seabreeze.spectrometers

print("opening...")
spec = seabreeze.spectrometers.Spectrometer.from_first_available()

print("found serial", spec.serial_number)

print("closing...")
spec.close()

I get the following exception instead of successfully printing the serial number of my USB-attached FLAME-S:
