Hi @satherev. The first thing that I noticed is that the error says HTTP GET request to http://redacted:5601/api/status fails (note http://) but you have TLS enabled in kibana.yml:
server.ssl.enabled: true
Could it be the setup.kibana.host was missing an s?
As a second check, are you able to reach Kibana successfully through that URL (i.e. web browser or other way)?
I would also suggest to check out some other similar topics:
