    ***SOLVED***
    The webGL app I have deployed is not working and I can not figure out what is wrong. I updated the editor, I changed some settings according to a few videos I found but they were aimed at deployment on itch.io. This is really frustrating me. I have deployed a webGL app in the past and did not have any issues. Any help would be greatly appreciated.

    This is the error code thrown by Firefox:

    I assume Build&Run locally works fine?
    Try deploying to Unity Play via the WebGL Publisher asset from the store. Or to itch.io. If that works, at least you know it‘s an issue with the webserver.
    Play with the build settings like compression. Be sure to deploy a debug build for testing.

    Thank you for pointing me in the correct direction. The issue was that the server was not configured for web assembly files (/wasm) and this was resolved by adding a htaccess file to the game directory as described in the Unity manual here.
