Hi!

I have Elasticsearch clusters behind NGiNX.  
Everything has worked great until I try to connect my Elasticsearch clusters with Liferay Client.

Liferay client is using Elasticsearch Native Binary Protocol to connect my cluster and NGiNX seems not to understand this. I have no problems with any java-based transport client going through NGiNX Stream.

If anyone could have a clue what option should be used with proxy to allow Elasticsearch Native Binary Protocol go through please help.

Using Elasticsearch 6.8.6  
Nginx 1.15.9  
Red Hat 7.7

nginx.conf  
---clip----  
stream {  
include /etc/nginx/conf.d/elasticsearch\_tcp.conf;  
}

elasticsearch\_tcp\_conf  
server {  
proxy\_buffer\_size 16k;  
listen 10.100.5.10:8090;  
proxy\_pass 10.20.1.10:9300;

So the Liferay client can connect to cluster without problems if NGiNX is removed. But not through this configuration. But all the other transport clients work without problems.
