Grafana failed using extrnal domain

Hi,

I’m setting up Grafana and if I’m on my LAN using the internal server DNS http://hassio.local:8123/ I can use Grafana. If using my external DNS via my Reverse Proxy (Sophos UTM) with an Let’s Encrypt Cerificate for my Home Assistant I get only this:

If you’re seeing this Grafana has failed to load its application files

  1. This could be caused by your reverse proxy settings.

  2. If you host grafana under subpath make sure your grafana.ini root_url setting includes subpath

  3. If you have a local dev build make sure you build frontend using: yarn start, yarn start:hot, or yarn build

  4. Sometimes restarting grafana-server can help

External I using home.mydomain.net to open Home Assiatnt and this is my Grafan config:

{
  "plugins": [],
  "env_vars": [
    {
      "name": "GF_DEFAULT_INSTANCE_NAME",
      "value": "Hassio"
    },
    {
      "name": "GF_SERVER_DOMAIN",
      "value": "home.mydomain.net"
    },
    {
      "name": "GF_SERVER_SERVE_FROM_SUB_PATH",
      "value": "true"
    }
  ],
  "log_level": "info",
  "ssl": false,
  "certfile": "",
  "keyfile": ""
}

Thank’s for any hint because I try days without getting it work.
