Nginx is unable to handle requests from custom domain

To resolve the issue where Nginx is unable to handle requests from your custom domain and serve your Laravel application, follow these steps:

1. Verify DNS Settings: Ensure that your domain (siyab.dev) is correctly pointed to your server's IP address. You can use tools like dig or online services like whatsmydns.net to verify DNS propagation.

2. Check Nginx Configuration: Ensure that your Nginx configuration files are correctly set up and symlinked. Based on your provided configuration, it looks mostly correct, but let's double-check a few things.

3. Nginx Configuration Files:

   • /etc/nginx/sites-available/mysite.com:

     server {
         listen 80;
         listen [::]:80;
         server_name www.siyab.dev;
         return 301 http://siyab.dev;
     }
     
     server {
         listen 80;
         listen [::]:80;
         server_name siyab.dev;
         root /home/laracasts/www/public;
     
         index index.html index.htm index.php;
     
         location / {
             try_files $uri $uri/ /index.php?$query_string;
         }
     
         location ~ \.php$ {
             fastcgi_split_path_info ^(.+\.php)(/.+)$;
             fastcgi_pass unix:/run/php/php8.2-fpm.sock;
             fastcgi_index index.php;
             fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
             include fastcgi_params;
         }
     }
     

   • /etc/nginx/sites-available/default:

     server {
         listen 80 default_server;
         listen [::]:80 default_server;
         server_name _;
         root /var/www/html;
     
         index index.nginx-debian.html;
     
         location / {
             try_files $uri $uri/ =404;
         }
     }
     

4. Symlink Configuration: Ensure that the configuration file is symlinked correctly in /etc/nginx/sites-enabled/:

   sudo ln -s /etc/nginx/sites-available/mysite.com /etc/nginx/sites-enabled/
   

5. Test Nginx Configuration: Test the Nginx configuration for syntax errors:

   sudo nginx -t
   

6. Reload Nginx: If the configuration test passes, reload Nginx to apply the changes:

   sudo systemctl reload nginx
   

7. Check File Permissions: Ensure that the Nginx user (usually www-data) has the necessary permissions to read the Laravel application's files:

   sudo chown -R www-data:www-data /home/laracasts/www
   sudo chmod -R 755 /home/laracasts/www
   

8. Verify PHP-FPM Socket: Ensure that the PHP-FPM socket path is correct and that PHP-FPM is running:

   sudo systemctl status php8.2-fpm
   

9. Check Laravel Logs: If the domain still doesn't serve the Laravel application, check the Laravel logs for any errors:

   tail -f /home/laracasts/www/storage/logs/laravel.log
   

By following these steps, you should be able to diagnose and fix the issue with Nginx not serving your Laravel application from the custom domain. If you encounter any specific errors during these steps, please provide the error messages for further assistance.
