I just fixed a situation where I couldn't get mpd to work over my home network.
I think it may be this same issue.
On my system
# sysctl net/ipv6/bindv6only
net.ipv6.bindv6only = 1
netstat would show init listening on [::]:6600 but doesn't report the
IPV6_V6ONLY socket state so I had missed there was no socket listening on ipv4.
Adding
[Socket]
BindIPv6Only=both
to the mpd.socket unit fixed my problem.
