More than 12 hours looking for the solution to have a multi-language store, in a Plesk Odin environment, based on Nginx server (without apache) + FPM

Dozens of posts in google, and no solution.

On my stage, and in order not to disturb my client, who insists (I do not know why) on using a Plesk control panel, I created in a VPS development, a fresh installation of Plesk, with a prestashop 1.7.5.2

Once installed and tested, it worked perfectly in Apache mode, without using nginx

Activation of Nginx (Apache deactivation)

It works as long as there are no languages.

If there're languages all links show

I use a official nginx.conf.dist with adaptations to Plesk interface, beacuase Plesk is a intrusive panel. This use a nginx.conf  with call to vhost_nginx.conf (content below)
