title: Kibana - Request Timeout after 30000ms at /usr/share/kibana/node_modules/elasticsearch/src/lib/transport.js:355:15
body: <p>Fresh installment of Kibana (On redhat 7.6 (64bit) via yum) starts, but is restarting every minute. Before it restarted every 5 seconds, but i fixed it after changing <code>/etc/fstab</code> to allow <code>noexec</code> on <code>/var</code> cause it is needed for <code>/var/lib/kibana/headless_shell-linux/headless_shell</code>.</p>
  
  <p>I tried starting Kibana by command instead of systemctl to see full logs:
  <code>/usr/share/kibana/bin/kibana -c /etc/kibana/kibana.yml</code></p>
  
  <p>It gives me output:</p>
