Does support for any version of elastic is work now?

./gor --input-raw :8080 --output-http http://x.x.x.x --output-http-elasticsearch 'http://elk:9200/gor' --input-raw-engine raw_socket --input-raw-track-response

--output-http is work (also work output to file/output to stdout), BUT

tcpdump 'dst port 9200' tcpdump: verbose output suppressed, use -v[v]... for full protocol decode listening on enp5s0, link-type EN10MB (Ethernet), snapshot length 262144 bytes

and silence...

I do not understand how can i connect to elastic. Or its support is not working now?

(i am try master and 1.3.3 versions)
