Does a

> curl -X GET "localhost:9200/\_cluster/health?pretty"

show a good cluster?

+1 to ^. On the Kibana side it's saying the socket hung up unexpectedly, some ideas worth looking into are self signed ssl certificates, that kibana's able to get a response in \< 3 seconds, a second pass at kibana.yml may help too if you want to share the http/ssl portion.

Quick question - is the server still active? There were some issues with over-verbose error logs in 6.8 that were limited to a single http requests so it may leave us with the request timeout.
