Make sure you're using JSON API plugin for Grafana | Grafana Labs
And include /api/getServers after host IP : unraid-api port (http://1.1.1.1:3005/api/getServers)

After spending 30 minutes struggling with this I found out that if your installation is on another network without direct LAN access your base url needs to be the proxied address, seems to be fetched from the browser instead of Grafana installation🙄
Thank you for making this project @falconexe. I suddenly enjoy my metrics
