Description of your problem Graylog no longer starts correctly. When I restart the application I get the following error from server.log in /var/log/graylog-server/: 2021-09-27T17:16:04.349Z ERROR [ServerBootstrap] Graylog startup failed. Exiting. Exception was: java.lang.IllegalStateException: Exp…

[image] hcomtes: nc -vz localhost 9000 I get connection refused if I use localhost but if I use the hostname I get: $ nc -vz G-Serv 9000 Connection to G-Serv 9000 port [tcp/*] succeeded! same issue with curl. I have to use the hostname and not localhost. I don’t see anywhere in the server.…

I would attach both server.conf and server.log but they exceed the character limit on this forum, and I can’t attach them to be uploaded due to your restrictions on file types. Let me know if you need them, and if so, how best to share them.

[image] hcomtes: server.conf and server.log but they exceed the character limit Try this: $ cat /etc/graylog/server/server.conf | egrep -v "^\s*(#|$)" Looks like it is a permission denied on a socket exception - at least that’s what I read out of it. Maybe you have some other service/appli…

Thanks for your response. Below is the server.conf file with password hashes removed: is_master = true node_id_file = /etc/graylog/server/node-id password_secret = root_password_sha2 = bin_dir = /usr/share/graylog-server/bin data_dir = /var/lib/graylog-server plugin_dir = /usr/share/graylog-serve…

Just to get things running, try binding to a different port, Graylog default is 9000… http_bind_address = 10.1.3.163:9000 If that works fine then it’s just figuring what else you have going at :80

When using port 9000, the error message doesn’t appear, and the server appears the start correctly: 2021-09-29T14:15:29.187Z INFO [CmdLineTool] Loaded plugin: AWS plugins 4.1.5 [org.graylog.aws.AWSPlugin] 2021-09-29T14:15:29.189Z INFO [CmdLineTool] Loaded plugin: Enterprise Integrations 4.1.5 [or…

I changed the port to 9000, and the application appears to start, but if I curl localhost:9000 I get “connection refused”. I can curl localhost:9200 I get elasticsearch responding, so I think this is an issue with graylog. The log says the graylog server is up and running, and the service is active…

Hey there. Catching up on the post, I’ll note that using :80 as your port is an antipattern. Anything below port 1024 is a privileged port and can’t be used without running Graylog as root, which we strongly recommend against unless you have a VERY good reason to do so. When it comes to curling loc…

I wasn’t aware running on port 80 wasn’t recommended, that’s fine, I can use a different port. My main issue is I’m still not getting a response through curl. When I run sudo netstat -ntlp | grep 9000 I get: tcp6 0 0 10.1.3.163:9000 :::* LISTEN 1380917/ja…

It just occurred to me that I think your mongodb_uri is incorrect. You currently have it set to: mongodb_uri = mongodb://localhost/graylog But given that MongoDB runs on 27017, your port is missing. It should look like: mongodb_uri = mongodb://localhost:27017/graylog This is likely why the curl’…

I get connection refused if I use localhost That’s really odd, but it seems to be the issue. If I use the IP with curl it works. So everything seems to be working fine on port 9000 now, but I’d like to have the site on port 80. I know you don’t recommend the application running on port 80. So what…

Best practice is to use a reverse proxy like Apache or Nginx. I’ve posted some Nginx examples here Nginx Config Examples
