React app not displaying on github pages

Hey everyone, I am having an odd problem that I hope has a simple solution. 
My react app is working fine on my localhost. But when deployed to github pages just gives me a blank page with lots of “Failed to load resource: the server responded with a status of 404 ()” 
As far as I can tell I cannot expand on this error and see where it’s coming from. 
Here is the link to my page

How do I get it to display my app? 
Thank you in advance for your help.
