I have installed ElasticSearch and Kibana (v 7.9.3) on a windows server.
ElasticSearch is available on port 9200.
I use reverse proxy on IIS for access to Kibana from outside. So I specified the server.basePath in configuration file (server.basePah: "/kibana" and server.host: "0.0.0.0"). So I can get Kibana from outside with "myServerUrl/kibana"
But when I want to create a new index pattern, kibana couldn't find any Elasticsearch data. Even if I have many index with docs. I can see all index in Index Management tab or by query "_cat/indices?v"
When I try to create new index pattern on localhost:5601 (by remove server.path) Kibana can find all index pattern available.
Why Kibana doesn't find any ElasticSearch data when I use server.basePath but can find data on localhost ?
