Hi, thank you for your reply.
Is that from
/var/log/kibana/kibana/log?
Yes, respectively from /var/log/kibana/kibana.log.
That should be
127.0.0.1:9200as Kibana uses the API and not the transport protocol.
That distinction really confuses me. I'm not sure whether I understood the answer in this thread correctly, but 9300 seemed to be the obligatory port to set and 9200 only an optional one. But maybe I got it the wrong way around.
Now that I've set the port to 9200 in the kibana.yml, the "systemctl status kibana" command reveals a running kibana service but also an error ECONNREFUSED. When I test the connection with curl, the command with port 9300 returns a valid answer, but the command with port 9200 only returns a "connection refused" error. How do I proceed from here to get the connection through?
