Graylog 4.0.1
I have been trying to resolve and issue where I am seeing the following repeated every few seconds in my Graylog server log:
2021-01-15T15:43:32.984-05:00 ERROR [PrivateNetLookupFunction] Could not run private net lookup for IP [-]: '-' is not an IP string literal.
I pulled out the graylog-plugin-threatintel-4.0.1.jar
file and restarted the server service and the ERROR goes away.
What is interesting is I am not currently using ThreatIntel and the error happens while the plugin is disabled on the Configurations page. Odd.
I would like to use it … eventually… has anyone seen this before?
