Hi Still getting same responce after adding above code.

Hello, is the problem solved? Try restarting nginx, using the browser in incognito mode or changing the browser to access it. Is the solution solved?

Hello, I suggest you provide more information or screenshots. I can’t tell what the problem is.
Is your website open? Can the backend of the website be opened?

    I have downloaded WordPress zip and upload on server then unzipped and create database .

      Hello, is it possible to try to modify the permanent link in the background of the website?

      Just Add it on Config not URL rewrite
      location / {try_files $uri $uri/ /index.php?$args;}

      Hello, would you like to add the content of line 52? Please check whether the configuration of the relevant site is configured correctly.
