Issue/Introduction

Trying to do a 'load_from_discovery_server' callback for device discovery in the snmpcollector probe.

Running the query from Probe Utility in Admin Console returns a fail as well as result "loadFromDiscoveryService() failed with errors.Check your probe LOG for details".

Upon checking the log, below are the errors found.

"Could not find discovery_server probe at {0}. Ensure the address is correct, and that the discovery_server probe is running.,args[string=No discovery server address defined.]

The discovery_server address is verified correct and other hubs have no issues running the same query.

Similar issue is around 10 hubs 

Environment

23.4 CU6 at Primary and Proxy hubs 

snmpcollector 4.15HF2

Remote third tier hubs at 9.37

Issue hubs had java 1.8 but old versions

Upgrade java_jre to latest 1.8 version from the Nimsoft archive fixes the issue
