This means the SNMP query is failing.  Possible causes:

1) Incorrect address for device
2) incorrect SNMP community
3) Network problem (no route to device, cannot ping...)
4) Firewall in the way
5) Device ACL refusing SNMP query from this host

Try doing a 'ping' from a command line - if it doesnt work. test your network links, routers, firewalls.
If you're sure the address and community are correct from tests on another machine, then check device ACLs to see if this host is allowed to use that community.
