All translated pages are gone, error 404, even after reinstalling wordpress

Hello, Hopefully someone can help

I worked on a wp site on a local host and used TranslatePress plugin to translate and it worked perfectly!
but when I migrated to the online host, suddenly I couldn’t access any translated page.
I feel this issue has something to to with the hosting service configuration, but I am only guessing.
I tried the plugin on a clean wordpress site (on the same domain) and it still gave me the same result.

If anyone knows what to do please reply
thanks in advance.
