I’m having issues with the graylog service. I have an nginx proxy sitting in front of graylog. When I navigate to https on my graylog host. I get the response below. If I run a curl from the host the service is running on to https://localhost:9000 I get the same java script as is being passed into my web-browser - so I don’t think the issue is nginx, I think it’s with graylog. I’m not quite sure how to troubleshoot from here. Any help would be great
Message from Graylog
Server currently unavailable
We are experiencing problems connecting to the Graylog server running on . Please verify that the server is healthy and working correctly.
You will be automatically redirected to the previous page once we can connect to the server.
Do you need a hand? We can help you.
Without knowing your configuration, at least the settings you have used for the res/web part ( http://docs.graylog.org/en/2.4/pages/configuration/server.conf.html#general ) nobody is able to guide you.
Thanks for the reply. I’ve posted my configs below - that is, everything that isn’t commented out.

did you use any kind of proxy or did you have graylog running on the computer you are currently using? because you bound the webinterface to localhost …
Does your nginx configuration follow: http://docs.graylog.org/en/stable/pages/configuration/web_interface.html#nginx
Keep an eye on
X-Graylog-Server-URL as this has to be the hostname/virtualhostname of your nginx.
Ahh - so I used the config from the document, but in my complete newb-ness I left the variables as variables rather than replacing them with their literal values. I replaced $server_name with the actual name of the server and that worked. Thank you so much for your assistance, I really appreciate it.
