DHT: starting
[1:32:48 PM]  DHT: attempting to listen for UDP on 0.0.0.0:12345
[1:32:48 PM]  DHT: attempting to listen for UDP on :::12345
[1:32:49 PM]  DHT: error listening: :::12345 Address family not supported
[1:32:49 PM]  DHT: UDP port bound OK.  Startup complete.

what does it mean: "Address family not supported"

if this is broken, how is it fixed?
