Hi. I have used ELK for audit mysql connection log & query log. A few days ago, I changed configuration of elasticsearch on elasticsearch.yml. - before : network.host: localhost - after : network.host: 10.xx.xx.xx ## And then, when I try to access kibana using web browser, following error occurred. [http://10.80.51.71:5601/](http://10.80.51.71:5601/) ## Fatal Error Kibana: Unknown error while connecting to Elasticsearch Error: Unknown error while connecting to Elasticsearch Error: Authorization Exception at respond ([http://10.xx.xx.xx:5601/index.js?\_b=7489:85288:15](http://10.xx.xx.xx:5601/index.js?_b=7489:85288:15)) at checkRespForFailure ([http://10.xx.xx.xx:5601/index.js?\_b=7489:85256:7](http://10.xx.xx.xx:5601/index.js?_b=7489:85256:7)) at [http://10.xx.xx.xx:5601/index.js?\_b=7489:83894:7](http://10.xx.xx.xx:5601/index.js?_b=7489:83894:7) at wrappedErrback ([http://10.xx.xx.xx:5601/index.js?\_b=7489:20902:78](http://10.xx.xx.xx:5601/index.js?_b=7489:20902:78)) at wrappedErrback ([http://10.xx.xx.xx:5601/index.js?\_b=7489:20902:78](http://10.xx.xx.xx:5601/index.js?_b=7489:20902:78)) at wrappedErrback ([http://10.xx.xx.xx:5601/index.js?\_b=7489:20902:78](http://10.xx.xx.xx:5601/index.js?_b=7489:20902:78)) at [http://10.xx.xx.xx:5601/index.js?\_b=7489:21035:76](http://10.xx.xx.xx:5601/index.js?_b=7489:21035:76) at Scope.$eval ([http://10.xx.xx.xx:5601/index.js?\_b=7489:22022:28](http://10.xx.xx.xx:5601/index.js?_b=7489:22022:28)) at Scope.$digest ([http://10.xx.xx.xx:5601/index.js?\_b=7489:21834:31](http://10.xx.xx.xx:5601/index.js?_b=7489:21834:31)) at Scope.$apply ([http://10.xx.xx.xx:5601/index.js?\_b=7489:22126:24](http://10.xx.xx.xx:5601/index.js?_b=7489:22126:24)) I executed netstat on this host. # netstat -an |grep 5601 tcp 0 0 0.0.0.0:5601 0.0.0.0:\* LISTEN tcp 0 0 10.xx.xx.xx::5601 10.230.xx.xx:55654 ESTABLISHED tcp 0 0 10.xx.xx.xx::5601 10.230.xx.xx:55653 ESTABLISHED tcp 0 0 10.xx.xx.xx::5601 10.230.xx.xx:55656 ESTABLISHED tcp 0 0 10.xx.xx.xx::5601 10.230.xx.xx:55652 ESTABLISHED What do I check to resolve this issue? ---

Do you have some kind of authorisation layer in your stack? ---

I just installed ELK and nginx. It don't have any authorization layer as I know. ---
