Nextcloud after well installation, doesn't want to work


I don’t what’s going on, but after well instalation, waiting, waiting and finally im always get “404 not found”. In my www link is “https://mydomain/cloud/nextcloud/index.php/apps/files/”. When i check it on server those files/directories exist. I tried everything i have no idea what’s wrong. Someone can give me some tips what should i check ? Im using nginx + php-fpm.

Thank you,

Do you use the nginx configuration from here?
