Overview
Some customers prefer that their origin servers are not publicly accessible, but this prevents imgix from be able to access images as well. If the service is unable to retrieve an image from the origin, then we will return a 404
error.
To resolve this, you can set up an allowlist to allow imgix to access your images.
User agent
The best method of making sure imgix can pull assets from your origin is by allowlisting our user agent. This is the recommended best practice for future compatibility.
Our user agent is: User-Agent: imgix/*
