Nginx config setting incorrect?

Question

Nginx

Hello!
There was a problem with nginx 1.14 configuration. I work in Open server panel. created two sites test.ru and testsite.ru in the domain folder. In the same place, in the domain folder, I created the catalog folder. In this folder, I created 2 folders test and testsite. and index files index.php in them. The config
for both sites is as follows:

server {
     listen			127.0.0.1:80;
    server_name    testsite.ru;
    index index.php;
    charset			utf-8;
    
    add_header 'Access-Control-Allow-Origin' '*';
  add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
  add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
  add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
    
    ssl_certificate               "%sprogdir%/userdata/config/server.crt";
    ssl_certificate_key           "%sprogdir%/userdata/config/server.key";
    
    location / {
        root       "F:\Server\OSPanel\domains\catalog\testsite";
        #try_files $uri $uri/ /index.php$is_args$args;
        try_files $uri $uri/ /index.php?$query_string;

        location ~ \.php$ {
            try_files                          $uri =404;
            # if (!-e $document_root$document_uri){return 404;}
            fastcgi_pass                       backend;
            fastcgi_index                      index.php;
            fastcgi_buffers                    4 64k;
            fastcgi_connect_timeout            1s;
            fastcgi_ignore_client_abort        off;
            fastcgi_next_upstream              timeout;
            fastcgi_read_timeout               5m;
            fastcgi_send_timeout               5m;
            fastcgi_param    CONTENT_TYPE      $content_type;
            fastcgi_param    CONTENT_LENGTH    $content_length;
            fastcgi_param    DOCUMENT_URI      $document_uri;
            fastcgi_param    DOCUMENT_ROOT     $document_root;
            fastcgi_param    GATEWAY_INTERFACE CGI/1.1;
            fastcgi_param    HTTPS             $https;
            fastcgi_param    QUERY_STRING      $query_string;
            fastcgi_param    REQUEST_METHOD    $request_method;
            fastcgi_param    REQUEST_URI       $request_uri;
            fastcgi_param    REMOTE_ADDR       $remote_addr;
            fastcgi_param    REMOTE_PORT       $remote_port;
            fastcgi_param    SERVER_ADDR       $server_addr;
            fastcgi_param    SERVER_PORT       $server_port;
            fastcgi_param    SERVER_NAME       $host;
            fastcgi_param    SERVER_PROTOCOL   $server_protocol;
            fastcgi_param    SERVER_SOFTWARE   nginx;
            fastcgi_param    SCRIPT_FILENAME   $document_root$fastcgi_script_name;
            fastcgi_param    SCRIPT_NAME       $fastcgi_script_name;
            fastcgi_param    TMP               "%sprogdir%/userdata/temp";
            fastcgi_param    TMPDIR            "%sprogdir%/userdata/temp";
            fastcgi_param    TEMP              "%sprogdir%/userdata/temp";
        }
    }
}

When you go to testsite.ru, it shows 404. The same goes for test.ru. If I change the name of the folder in catalog test to 2test and edit the root config to "F:\Server\OSPanel\domains\catalog\2test"; everything is fuming. The same goes for the second site. What's the magic? Where is the mistake?
