Wordpress permalink and cache help

Server NGINX
1

Hello, I have a wordpress website and want to enable caching. My
configuration below is working if no pretty url E.g.

But when I use pretty url, the cache doesnt work: E.g.
http://domain.com/sample-page

But the pages displays correctly for both cases.

Thank you
