Whenever starting Kibana I am getting the following errors in endless loop:

```
{"type":"log","@timestamp":"2017-01-15T13:01:28Z","tags":["warning","elasticsearch"],"pid":65037,"message":"No living connections"}
{"type":"log","@timestamp":"2017-01-15T13:01:31Z","tags":["warning","elasticsearch"],"pid":65037,"message":"Unable to revive connection: https://localhost:9200/"}

or

```
{"type":"log","@timestamp":"2017-01-15T13:02:28Z","tags":["warning","elasticsearch"],"pid":65082,"message":"Unable to revive connection: http://localhost:9200/"}

{"type":"log","@timestamp":"2017-01-15T13:02:31Z","tags":["warning","elasticsearch"],"pid":65082,"message":"No living connections"}

```

What is the issue? I can't find it.

Thanks

This happens when Kibana can't communicate with elasticsearch. Can you try pinging elasticsearch with curl from the box that kibana is running on?

```auto
curl -i http://localhost:9200

```

Below you can see the answer from curl command :

```
 mpswrk1@eaasrt!MPS:/etc/elasticsearch> curl --cacert /etc/elasticsearch/x-pack/elasticsearchcrt/elasticsearchcrt.crt https://localhost:9200
    curl: (60) Peer's Certificate issuer is not recognized.

```

What is wrong here?

Thanks  
Sharon.

Not sure about that curl error. Have you googled it? If you resolve that error I bet Kibana will start working again

</div>

mpswrk1@eaasrt!MPS:/etc/elasticsearch/x-pack\> `sudo curl -XPUT -u elastic:elastic 'https://eaasrt:9200/_xpack/license' -d @/etc/elasticsearch/x-pack/license.json`  
curl: (60) **Peer's Certificate issuer is not recognized.**

Why my peer certificate issuer isn't recognized?

I used the elastic certgen command to generate the certificated.

Also When I did it with RSA I got the same error.

Something is problematic here but I can't put my hand on it.

Any idea?

Now, I think my elastic is working, but still I can't open my browser for kibana

```
mpswrk1@eaasrt!MPS:/etc/elasticsearch> sudo curl --cacert /etc/elasticsearch/x-pack/localhost.cert -XGET -u elastic:myelasticpass 'https://eaasrt:9200'
{
  "name" : "mps",

  "version" : {
    "number" : "5.0.1",
    "build_hash" : "080bb47",
    "build_date" : "2016-11-11T22:08:49.812Z",
    "build_snapshot" : false,
    "lucene_version" : "6.2.1"
  },
  "tagline" : "You Know, for Search"
}
```
