Another important consideration is setting the hostname correctly when your server is behind a proxy. At the UNA level, the hostname could either be localhost or your domain name, depending on the installation method. If the hostname is not configured properly, images and media files may fail to process. This configuration is dependent on both your web server (such as Nginx or Apache) and server-level settings. It’s unlikely that this issue is related to Varnish or any other caching system. However, if you provide logs and details of your setup, we may be able to investigate further. Without additional information, it's difficult to pinpoint the exact source of the issue.
