Kibana unable to retrieve connection

Elastic Stack Kibana
1

Hi,

I have set up an ElasticSearch cluster which is using x-pack security. I have setup the initial user passwords, elastic and kibana. From the Kibana server, I can connect to the ElasticSearch cluster using the kibana username and password thus:

curl -k -u kibana:username https://owadata:9200

but when I try and connect to kibana I get no answer:

curl -k -u kibana:username https://kibanaserver:5601

The kibana.yml file has the following:

server.port: 5601
server.host: admin
server.name: admin
elasticsearch.url: "https://owadata:9200"
kibana.index: ".kibana"
kibana.defaultAppId: "home"
elasticsearch.username: "kibana"
elasticsearch.password: "passwordvalue"
logging.dest: /var/log/kibana.log
logging.silent: false

The value of passwordvalue is correct

In the log file, I get the following messages:

{"type":"log","@timestamp":"2018-05-23T13:35:51Z","tags":["license","warning","xpack"],"pid":2170,"message":"License information from the X-Pack plugin could not be obtained from Elasticsearch for the [data] cluster. Error: No Living connections"}

{"type":"log","@timestamp":"2018-05-23T13:36:00Z","tags":["warning","elasticsearch","admin"],"pid":2170,"message":"No living connections"}

I have applied the correct license to the elasticsearch cluster

Any ideas?

Are you sure elasticsearch is up and running? The logs indicate that kibana is failing to connect with it. It would be a different error message if the license or credentials were wrong.

Can you navigate to https://owadata:9200/ in the browser and connect to it?

Do you have ssl settings configured?

Hi Stacey,

Thanks for the info. I've got it working now. I hadn't specified the ca and certificate for the elastic search cluster.

Regards,
Kenneth
