When I open dashboard in grafana within home assistant and I copy URL in “Share”, that URL is not working in other browser window, even when I replace “localhost” with actual IP address, like: “http://35.98.255.198:3000/api/hassio_ingress/vIyQ8…”, I get UNREACHABLE. This seems to be problem of HA version 2024.12, it worked before update.
Found the solution. In Grafana add-on settings, I need to open port 3000 for docker. Just add 3000 to Network “Change the ports…” setting
