There could be quite a few reasons.
Make sure SNMP is running on the server you are trying to connect. (nmap -sU 172.30.16.132 -p 161 -sV -PN)
Make sure the community string that you got is correct. (maybe its canopy instead of Canopy)
Make sure you are using the correct SNMP version. ( it could be v2c or maybe v3)

Have you configured snmpd? If so how does it look like? Check out the man for snmp.conf
