Graylog Central (peer support)

I already reviewed topics like Web Interface Connection Refused and similar with no luck.

1. Describe your incident:
Whe accessing graylog web interface at http_bind_address and port stated there (taken from server.conf) i get connection refused error in browser
i do have network connectivity with that host

2. Describe your environment:

  • OS Information: Ubuntu 22.04.2 LTS VM

  • Package Version: Graloy 5? how to check this?

  • Service logs, configurations, and environment variables:
    /etc/graylog/server/server.conf i have set all basic settings seem needed for this

3. What steps have you already taken to try and solve the problem?
reviewed other topics but they were usually about older versions

4. How can the community help?
Provide step by step troubleshooting to run graylog properly and access the web interface succesfully. Im quite newbie so please be straighforward and assume no experience.

2

Can you share your server.conf file (you can remove the password and secret hashes).

Also can you share the last 100 lines or so of your server.log? It sounds like graylog isn’t starting up successfully.

couldnt paste cause of limit and cannot attach txt unfortunately:
"
Sorry, the file you are trying to upload is not authorized (authorized extensions: jpg, jpeg, png, gif, ico, mp4, pdf, mp3).
"
how do i attach server.conf then?

5

Something like https://pastebin.com/ may work.

It looks like your elaticsearch/opensearch cluster is not available.

Is it installed on the same server as graylog? Can you verify the service is running?

what do you get when you run curl localhost:9200 on the server where elasticsearch/opensearch is installed?

6

Is elasticsearch or opensearch installed on the same server as graylog?
Please be reassured that the opensearch or elasticsearch service is running.
Can you send us a copy of the server.conf file?

7

“Is elasticsearch or opensearch installed on the same server as graylog?”
Yes, it is.
" Please be reassured that the opensearch or elasticsearch service is running."
How to ensure that?
" Can you send us a copy of the server.conf file?"
it seems that limitation on this forum won’t let me, how should i do that to put here essential information?

8

To check the service run this command:
systemctl status opensearch
systemctl status elasticsearch

check server.conf with this commmand:
grep -E -ve “^#|^$” /etc/graylog/server/server.conf | grep elasticseach
