Reverse proxy behind nginx docker container not working Kibana 6.2.3

@jarpy @spalger, I have an update. I am getting a 200 from kibana (with the configs shared – sorry for my mistake).

It appears that the path is not getting altered by the kibana.yml. I thought the server.basePath would append the value provided to the path, such that if I request https://foo/kibana, I'd get back, https://foo/kibana/app/kibana/etc, instead if I request https://foo/kibana, I get back https://foo/app/kibana.

Thank you for your patience with my mistakes, again any guidance you can provide, would be greatly appreciated.

This curl is from the nginx host:

# curl http://kibana:5601
<script>var hashRoute = '/app/kibana';
var defaultRoute = '/app/kibana';

var hash = window.location.hash;
if (hash.length) {
  window.location = hashRoute + hash;
} else {
  window.location = defaultRoute;
}</script>#
