[ The below may not answer your question but may be worth addressing ]

Why this syntax?  It doesn't look right to me.  If the wildcard
address is bound, surely it isn't possible to also bind 0.0.0.0.

Just leaving out "listen-on" will automatically listen on all
interfaces, (separate listeners per interface are I believe still
needed for reliable IPv4 UDP operation).

Even if you only have a single non-loopback interface, this looks
a bit odd to me.
