Getting Error

I have a react app I’m trying to run but I’m receiving 

northcrypto1.github.io/:1 GET https://northcrypto1.github.io/pigeonapp/static/css/main.042abc20.chunk.css net::ERR_ABORTED 404

I’m running the site using the gh-pages branch on https://github.com/NorthCrypto1/pigeonapp/tree/gh-pages

I’m not sure how to fix this.

I have not been able to solve it. I tried redoing new repositories with generic react apps and still nothing. I don’t know how to solve this. I’m getting Failed to load resource: the server responded with a status of 404 () now as an error
