I have found several issues on Grafana’s Github page. However, none of them worked. I’m using nginx (actually is [nginx-proxy by jsonwilder](https://github.com/jwilder/nginx-proxy)) What I want to do: Consume Grafana API from my very own backend/frontend. I’m creating a system that will consume grafana api and load render images from selected dashboard (and panels) and send a e-mail with them. What issues i’m having: CORS problem. I can’t consume Grafana API from my backend and from my frontend cuz of cors. What I’m trying to do: Using nginx reverse proxy I can’t set the CORS header to enable the communication. However, the reverse proxy seems to be working OK. When I send request to the nginx-proxy, they are redirected to grafana endpoint and everything works. Howerver, I can’t assure if the header is been setted. ---

Generic answer (because no exact request/error is provided): [https://enable-cors.org/server\_nginx.html](https://enable-cors.org/server_nginx.html) You may need to customize this config - check preflight request what is requested and customize accordingly.
