Memcached application issue NAN

Running LibreNMS via docker.
memcached graphs are being generated but all NAN.

The /etc/snmpd/memcached is pulling data fine.
The /etc/snmpd.conf:
extend memcached /etc/snmp/memcached

snmpd daemon was restarted.

I don’t know where to go from here as far as troubleshooting and could use some any pointers.
Thanks,
P
