Check to see if the Collector is up and running in Settings -> Server -> Collectors, then restart the Collector.

Can you telnet from this machine to localhost:9998 ?

Is localhost resolving to 127.0.0.1? (try pinging it)

Connection refused means that you can connect to the system (not surprising since it's localhost!) but there's no process listening on the specified port.

My guess is that the Collector is not running. Another possibility is that you changed the Collector agent listening port -- you can check that in Settings -> Server -> Collectors. In fact, that would be a good place to start, to see what is running on what port.
