If you're seeing this Plutono has failed to load its application files

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

2. If you host plutono under subpath make sure your plutono.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 plutono-server can help
