Kibana 502 Bad gateway in logs

Elastic Stack Kibana
1

Hi,

I have successfully installed kibana 5.2 with ES 5.2. I am able to open the UI page but nothing seems to be visible. Just an empty page. Looking at the kibana logs i see the following error. I have no idea what does it mean and why is it feeling. But can tell that it is failing with a 502 bad gateway error. Can anyone point me to the solution.

Thanks @weltenwort for replying back.

It was a missing port number in kibana.yml file pointing to ES URL. In my case i just mentioned it as

elasticsearch.url: "http://example.com"

where as it should be

elasticsearch.url: "http://example.com:9200"
