Getting Kibana Error: Please ensure that Elasticsearch is reachable from your system

Elastic Stack Elasticsearch
1

I have the following setup:

Application Server with NGINX and Kibana and configured as reverse proxy
Two node Elasticsearch cluster
Both hosted on EC2

When I try to query Elasticsearch through Kibana from behind a corporate
firewall I get the following error message:

"Could not contact Elasticsearch at http://IP:9200 Please ensure that
Elasticsearch is reachable from your system.. "

I presume that the issue is down to port 9200 being closed in the firewall.

Are there any solutions to this (without changing the firewall settings or
putting ES on port 8080 or similar)

Thanks a lot

Without changing a firewall setting on the IP address you're trying to
connect to? Or changing to a port that is already open?

IMO it has to be open, there is no alternative. Someone may opine
differently, but from what I've seen Kibana does not support a transport
other than IP (like pipes).
If you have ES running on the local node, then you can open the port on the
local machine.

IMO,

It'd probably depend on your nginx setup. If you can gist it it'd help.

We use a reverse proxy so the users browser doesn't do a direct connect to
ES, and this works fine.
