Moving a 1-click ghost installation to a subdirectory getting 404 error.

Hello,

I am trying to run a ghost blog in a subdirectory(/blog) instead of the direct domain link. I have changed the location from /etc/nginx/sites-available/site_name.conf

server {
   listen 80;
   listen [::]:80;

   server_name domain.com;
   root /var/www/ghost/system/nginx-root;

   location ^~ /blog {
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Proto $scheme;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header Host $http_host;
       proxy_pass http://127.0.0.1:2368;

   }

   location ~ /.well-known {
       allow all;
   }

   client_max_body_size 50m;
}

and changed the config.production.json file to:

 production: {
        url: 'http://example.com/blog/',
        mail: {},
        database: {
...

and then I restarted the server

sudo service nginx restart

it has been moved to /blog but it doesn’t show me the posts, images, footer, admin page /ghost link etc., perhaps it’s about MySql but I couldn’t find a way to solve it, may someone direct me how can I solve it?

Thank you,
