SNMP Setup

Having a few issues setting up a device for SNMP. I know it should work as I have other devices using SNMP. However Anturis keeps giving me this error:

Target
retries: 3
attempt_timeout: 20000
oid: 1.3.6.1.4.1.3224.1.29
community: Monitor
host: 192.168.76.254
version: 1
timeout: 300000
Agent error
Error 1008: SNMP Unexpected Response Received
Bad or unexpected response received from SNMP server on the target host. Check if it is configured properly.

What am I missing?
