We require a somewhat modern browser with these following features:

On some privacy-hardened browsers, you might have to enable the "Javascript JIT and WebAssembly" permission, as well as the "WebGL" permission.
Opening the console

You can open the console with the following keybinds:

On Firefox, you can try to see in the "Network" tab if a request failed. This is similar on Chrome.
If a request failed, try refreshing the page or trying again later.
If you see an error in the console tab, then that might indicate a problem in the software itself.
You can report it to the developer by submitting a bug report issue: https://github.com/Not-A-Normal-Robot/keplerian-sim-demo/issues/new

Opening the console is not very easy in mobile and is out of the scope of this guide.
