Environment

• WordPress 5.1.1
• Nginx 1.15
• PHP-FPM 7.2
• wp-supercache

Here is how I fix it:
#vi /etc/nginx/wp-supercache
Original:

location / {
    try_files $cachefile $uri $uri/ /index.php;
}

Changed to:

location / {
	try_files $cachefile $uri $uri/ /index.php$is_args$args;
}

Restart Nginx to apply the changes:

# sudo systemctl restart nginx
