Try a newer browser before anything else! I was using an older version of Safari on Mac and got 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. If not using a reverse proxy make sure to set serve_from_sub_path to true. 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 5. Check if you are using a non-supported browser. For more information, refer to the list of supported browsers. |
I switched to the latest version of FireFox and was fine.
