Hi Himanshu, you configured Graylog to use port 12900 for the REST API. The API needs to be directly accessable by your browser. To do so you can use either the web_endpoint_uri _or_ the X-Graylog-Server-URL in your proxy config. You set both but with two different url's. Use just the one in the Nginx config and set it to the correct REST url (from the perspective of your browser)
