I have a page redirect that works locally but not on netlify

so I have all my redirections that work except one, when I click on a button, I launch a window.open(MYUrl);
and I get a 404 error from you or when I do the same thing locally by modifying the url with localhost of course it works
here is the url of my site: https://cailletquentin-portfolio.netlify.app/
here is the url in 404: Caillet Quentin | Portfolio

Hi @Altx

I’m a little confused.

Where it the button that gets clicked? Is this the one on the Games page?

How is the redirect implemented?

This path works for me https://cailletquentin-portfolio.netlify.app/gameAsteroids
