Images cannot be uploaded to tickets or the knowledge base on an NGINX install. Upload appears to succeed (302) but image does not display and returns 404.

NGINX does not support osTicket out of the box -- it requires manual rewrite/location block configuration. Add specific location blocks to your NGINX site config with fastcgi_split_path_info and PATH_INFO support for file.php and scp/ajax.php. Use the recipe from: https://web.archive.org/web/20240511013836/https://www.nginx.com/resources/wiki/start/topics/recipes/osticket/ -- or switch to a natively supported web server (Apache, LiteSpeed, IIS).
