page deployed but paths doesn't work

Hi,

I deployed my page (https://lberthaut.github.io/projetsportsee/), and put component's paths with Routes. The homepage is goodly deployed but I should be able to change pages by adding a uri (12 or 18 by choosing one of the two first names on the homepag). But when I do, a github 404 error is displayed. In localhost, I have not this matter.

React-gh-pages should handle this or is it not supported? did I make a mistake during deployment?
