I have an issue with the clean urls check. When I test there is an error in the Nginx log:

2017/10/06 09:49:01 [error] 468#468: *199 open()  "/usr/share/nginx/html/drupal-7/admin/config/search/clean-urls/check" failed  (2: No such file or directory), client: 192.168.1.254, server: localhost,  request: "GET /drupal-7/admin/config/search/clean-urls/check HTTP/1.0",  host: "localhost". 

I don’t know if it is a nginx problem or a Drupal problem.

update : i change some things in the nginx.conf now i have an error in the log of nginx : 2017/10/14 21:55:08 [error] 4804#4804: *1 directory index of “/usr/share/nginx/html/drupal-7/” is forbidden, client: 192.168.1.254, server: localhost, request: “GET /drupal-7/?q=admin/config/search/clean-urls HTTP/1.1”, host: “localhost”. Here is my nginx.conf :
