user error? or library?

[spencercap]

Hi- so happy this library exists, would love to get it working!

somehow i'm caught up at even the simplest sweep for devices on my network (LifxLAN().get_lights())

i'm on a mac running 14.3.1 w/ python v 3.12.4 i AM able to ping my devices' IPs from terminal (though 2 show up in my router's device list with 1 final digit different, 1 of them is ping-able)

here are the errors i'm seeing, any help would be rad! cheers

ah, solved (ish) downgraded to python v 3.6.15 and it works as expected.

didnt mess about further to find which version it breaks at
