Nuxt | Problem with page source and Redirecting

I use nuxt-generate to build a static website and now it's running on static hosting.

Problem: when I try to load a page like example.com/page1 on a new webpage, it loads the index (example.com), not the page I wrote. And when I look at the page source of every page it loads the index page source.

How can i fix this problem? Thanks.
