🐛 How I Ran Into This

While integrating a newsletter service, I encountered an unexpected issue with email confirmation using Laravel signed URLs. Strangely, it worked flawlessly in my local environment but failed to function properly in the production environment.

✅ Solution

Upon investigation, I identified a misconfiguration in the Nginx setup. Enabling HTTPS within FastCGI resolved the issue. Here's the corrected Nginx configuration:

location ~ \.php$ {
    fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
    fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
    fastcgi_param HTTPS 'on'; # HTTPS enabled here
    include fastcgi_params;
}

By explicitly enabling HTTPS within the FastCGI parameters, I ensured that Laravel's signed URLs functioned correctly in the production environment.
