Yet another Blank Page after fresh install

Support Installation & Hosting
1

I know this is a common problem. i’ve read multiple posts about it, but none of them worked for me.

I have a fresh install of Grav running locally, just to test it. It is running over Nginx.

When i start it over nginx, with a custom server_name, it gives-me a blank page. by going on localhost, i am met with the error " InvalidArgumentException
The directory “/var/www/html/grav/cache/doctrine/9565bf08” does not exist and could not be created.".

I dont think the problem is with nginx. i created a php.php and a index2.html to test it and it works.

on the other hand, when i use the grav bult-in web server, it runs perfectly.

what is wrong?

here is my nginx conf

server {
    index index.html index.php;
    root /var/www/html/grav;
    server_name grav.localhost;
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~* /(\.git|cache|bin|logs|backup|tests)/.*$ { return 403; }
    location ~* /(system|vendor)/.*\.(txt|xml|md|html|htm|shtml|shtm|json|yaml|yml|php|php2|php3|php4|php5|phar|phtml|pl|py|cgi|twig|sh|bat)$ { return 403; }
    location ~* /user/.*\.(txt|md|json|yaml|yml|php|php2|php3|php4|php5|phar|phtml|pl|py|cgi|twig|sh|bat)$ { return 403; }
    location ~ /(LICENSE\.txt|composer\.lock|composer\.json|nginx\.conf|web\.config|htaccess\.txt|\.htaccess) { return 403; }

    location ~ \.php$ {
        include /etc/nginx/default.d/*.conf;
    }

}

The issue you’re experiencing is likely related to directory permissions. The error message indicates that the server cannot create the required directory under /var/www/html/grav/cache/doctrine.

To resolve this, first check and update the permissions for the cache directory and its parent directories.

i chmod the whole /www/html/grav folder to 777. the problem persists.

as i said, it works with the built-in webserver, but not with nginx, for some reason.

and even that error, it only appears on localhost, but the server_name i assigned is grav.localhost, which is blank

this is the nginx log. as i said, it is all 777, and chown is $USER:nginx
