Wordpress + Nginx. How to make links like site.ru/post.html?

Question

Nginx

Not so long ago, after the updates, I can’t say what exactly the links on one site were broken, they looked like site.ru/post.html after the update, when you click on these links, it gives error 404, I had to bring the links to the site.ru/post/ look, I want to go back as it was. Tell me if there is a solution, I did not find it myself.
My NGINX site.conf config

nginx site.conf

nginx version: nginx/1.13.1
PHP v 7.1.5
MysQL v 5.7.18
PS: Problem solved. Found the solution here on toaster

if (!-e $request_filename ) { rewrite ^(.*)$ /index.php?q=$1; }

If anyone has other options please share.
