This is almost definitely due to the access configuration of the agent. Many pre-configured systems (such as most Linux distributions) will only allow access to the system group by default, and need to be configured to enable more general access.

The easiest way to test this is to try a GETNEXT request on one of the other standard groups e.g.

       snmpgetnext .....  interfaces

If the agent responds with "hrSystemUptime.0" or "end of MIB", then it is clearly configured in this way. See the entries on access control in the AGENT section for more information.
