Hello All,

I am trying to execute mt Kibana UI login and it fails.

I checked the logs for the pod and this is what it shows:

[lewellf\_adm@awva-pclif03001 kibana]$ kubectl logs kibana-75f647cf75-5l5lz -n monitoring-tools

Can someone please help me fix this issue?

Greatly appreciated!

Hello @FREDDIE2020, can you please check what is specified in your _/etc/kibana/kibana.yml_  
`elasticsearch.hosts: http://es.domain.tld:9200`

And try to test if from the Kibana node using curl:  
`curl http://es.domain.tld:9200`

@stmx38

So kibana.yml does have the elasticsearch.hosts entry defined correctly but cannot do curl from pod.

Any suggestions?

Thanks,

Thanks. I was able to resolve my issue by deleteing kibana setup and re-applying using kubectl.
