Basically, that’s it. I’m getting this error on graylog’s internal log and have no idea how to solve it - Google gives me the first entry as the ThreatIntel plugin github
and the rest are two Cisco results, an OpenDNS, and other unrelated stuff.
I remember installing the ThreatIntel plugin, because @ionstorm’s Syslog threat intel pipeline uses it, but this error didn’t used to appear… and I think it started right after applying the omnibus to 2.2.3-2, from 2.2.3-1 OVA.
