<p>I'm setting up ELK services in Azure Kubernetes Service. But I only see this error:</p>

<blockquote>
  <p>"Kibana server is not ready yet"</p>
</blockquote>

<p>I'm using Helm to install the stable/elastic-stack release without any changes (default for everything) in AKS.</p>

<pre><code>helm install --name elk stable/elastic-stack
</code></pre>

<p>And I also added an ingress controller to expose the Kibana server to public.
However, I only see "Kibana server is not ready yet" error.</p>

<p>I've checked the Kibana pod is running, as well as the ElasticSearch. As a newbie in Kubernetes, I have no idea about how to find the error log in Kibana instance. Can anyone help me on this? It is also appreciated if you can indicate what step I am missing.</p>

<p>It might be the version incompatible issue. Just follow the console to get the errors.
Kibana version should be always higher than Elasticsearch.In that case, it gives an error following.</p>

<p>[error][status][plugin:xpack_main@7.4.0] Status changed from yellow to red - This version of Kibana requires Elasticsearch v7.4.0 on all nodes. I found the following incompatible nodes in your cluster: v7.1.1 @ 127.0.0.1:9200 (127.0.0.1)</p>
