Nginx - same server, one specific path to a different root folder

I am having a hard time trying to figure out how to configure Nginx. Basically, I have the same server name, but two websites:

1. website x root folder: /var/www/html/x/public
2. Wordpress root folder: /var/www/html/wordpress

When I access localhost:8443 it will go to: /var/www/html/x/public when I access localhost:8443/blog it will go to: /var/www/html/wordpress

I managed to make it work up to a certain point where localhost:8443/blog works but localhost:8443/blog/my-blog-post doesn´t.

server {
    listen [::]:443 ssl http2 ipv6only=on;
    listen 443 ssl http2;
    server_name localhost;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";    

    charset utf-8;   
    
    index index.php;  
    root /var/www/html/exploraai/public; 

    location ^~ /blog {            
        alias /var/www/html/blog;  

        location ~ \.php$ {
            try_files $uri = 404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass php:9000;
            fastcgi_index index.php;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $request_filename;
            fastcgi_param PATH_INFO $fastcgi_path_info;
        }   
    }  

    location / {  
        try_files $uri $uri/ /index.php?$query_string;     
    }

    location ~ \.php$  {                 
        try_files $uri = 404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }   

    location ~ /\.(?!well-known).* {
        deny all;
    }

    location = /favicon.ico { 
        access_log off; log_not_found off; 
    }
    location = /robots.txt  { 
        access_log off; log_not_found off; 
    }

}

I tried different things, but so far nothing worked.

Update

What worked for me was replacing the location blog for the following location block

location /blog {        
    alias /var/www/html/blog/;  

    try_files $uri /blog/index.php;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }   
}
