Cannot access Kibana on port 5601

Elastic Stack Kibana
1

Greetings,

I hope this is correct section for this kind of problems.

Browser on http(s)://domain.name:5601 returns ERR_CONNECTION_RESET.
If I do curl http://127.0.0.1:5601, I get empty response, nothing, no error.
Error log in /var/log/ doesnt exist.

Few starting infos:

  • curl 127.0.0.1:9200:

    "cluster_name" : "elasticsearch",

if you execute curl -I http://127.0.0.1:5601 do you see a response similar to the following

HTTP/1.1 302 Found

I get this:

Great! Then Kibana is listening on localhost:5601. Can you try doing the same curl request using the ip address of the "public" network interface both on the Kibana server itself, and the computer that you're running the web browser from?

5

I get same result with command ran on server.

I guess some FW is messing with outside access tho, I'm not sure which one, since I have it turned off..

6

It's possible that your internal network is configured to prevent the two hosts from communicating at all.

Well, thank you for now, will go research my network topology..
