Kibana not IPv6 ready

Elastic Stack Kibana
1

To me it looks like Kibana is not IPv6 ready.

The node im running elasticsearch and kibana on only has ipv6 addresses and kibana is failing while all ports are reachable.

Error: unhandled courier request error: No Living connections

Can you provide some of the logging from Elasticsearch and Kibana as they start up?

And what versions they are.

For Elasticsearch the logging that shows the listening info like;

[INFO ][node                     ] [Rancor] starting ...
[INFO ][transport                ] [Rancor] publish_address {127.0.0.1:9300}, bound_addresses {127.0.0.1:9300}, {[::1]:9300}

[ERROR][license.plugin.core      ] [Rancor]

And for Kibana (I stopped my Elasticsearch instance in this case);

 [info][listening] Server running at http://0.0.0.0:5601
 [error][elasticsearch] Request error, retrying -- connect ECONNREFUSED 127.0.0.1:9200

I'm using IPv6 exclusively for my setup:

ElasticSearch:

network.host: ::1

Kibana:

server.host: "localhost6"
elasticsearch.url: "http://localhost6:9200"

Works fine.
