I just realized my pleroma instance has been broken for several days and was unable to federate my statuses. People were not just ignoring me in the end :DLesson learned: if you have a working IPv6 setup, redirecting some incoming Nginx traffic to localhost:listeningPort will silently fail if your proxied service is actually listening on 127.0.0.1:listeningPort.Either make your service listen to [::] as well or explicitely point to 127.0.0.1 instead of localhost.
