Nuxt showing 404 page This page could not be found Back to the home page during a shot moment

I made a website using Nuxt, Tailwind and i18n. It's perfectly running locally (with nuxt build and nuxt start), but when I deploy it (with the same commands) on the server of a hosting company, every page except the "root" one is showing an error (this page could not be found) during half a second; before being replaced by the content of the page. But when I look at the HTML page, the content is the one of an error page. (contains "This page could not be found"); while it's not the case locally. Here is en example : https://jimmy.cf/contact Do you have any idea of where my problem could come from ? Thanks a lot !
