Server returns blank page with 404 status code

[Silveere]

Describe the Bug

When attempting to access the application through my web browser, I only receive a blank page with an HTTP status of 404. I can confirm that this isn't a network configuration issue, as it actually establishes an HTTP connection, and I can also access all of the APIs without issue. I am not utilizing any reverse proxy, I am connecting directly to the configured port.

Reproduction Steps

1. Create a new server with minimal mods installed.
2. Start the server.
3. Connect to the locally created web server.
4. The application doesn't load and just shows a blank page with a 404 status code in the dev console.

Expected Result

The application should load.
