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](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 uli -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

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.

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.
