The Kibana Dashboard is empty, despite of Logstash receives the netflow traffic. The logstash log has the following prints : [DEBUG][org.logstash.filters.GeoIPFilter] IP not found! exception=com.maxmind.geoip2.exception.AddressNotFoundException: The address 48.0.0.144 is not in the database., field=[netflow][src\_addr], event=1970-01-02T02:50:21.000Z 192.168.100.2 %{message} [DEBUG][logstash.filters.geoip] IP 48.0.0.144 was not found in the database {:event=\>#LogStash::Event:0xf04f397} Everything worked fine until I restarted the computer. before restarting I saw the sent netflow messages in Kibana : ![image](https://us1.discourse-cdn.com/elastic/original/3X/9/2/927ff6f2116a9b446323d645962d9e7ccf9ec5be.png) The logstash input config is input { udp { host =\> "10.213.79.240" port =\> 2055 codec =\> netflow } } Could please explain, what happened and how to fix the problem thanks ---
