spiceproxy only listening on IPv4 not IPv6

[hvisage]

Good day,

Is there a reason why spiceproxy is only listening on IPv4 and not also IPv6?

# ss -tnlp|grep -i proxy
LISTEN    0         128                0.0.0.0:3128             0.0.0.0:*        users:(("spiceproxy work",pid=8375,fd=6),("spiceproxy",pid=8374,fd=6))
LISTEN    0         128                      *:8006                   *:*        users:(("pveproxy worker",pid=27498,fd=6),("pveproxy worker",pid=27497,fd=6),("pveproxy worker",pid=27496,fd=6),("pveproxy",pid=27495,fd=6))

Do you have an entry in your /etc/hosts file with your node and the IPv6 address? AFAIK the spiceproxy is checking that to determine on which IP to listen.
