You configured snmpd to listen on ::1, but you
asked fe80::3e97:eff:fe8b:f326. It's not listening
on fe80::3e97:eff:fe8b:f326, so it will not respond. As you say, when you
make your request to ::1, it works.
"udp6:[::1]:161" is the equivalent of "udp:127.0.0.1:161". If you want to
listen to the wildcard, you don't specify an address -- just use "udp6:161".
