Description
I am running image proxy behind nginx. Images are proxied for most blogs, but not for posts coming from Substack.
Here is an example image:
<img

When I navigate to this image in the browser, I get requested URL is not allowed.
The image proxy logs show
request does not contain an allowed host or valid signature: https://substackcdn.com/image/fetch/w_1456,c_limit,f_webp,q_auto:good,fl_progressive:steep/https:/substack-post-media.s3.amazonaws.com/public/images/4039c96c-41b9-4451-9814-90c95dd4cf22_600x600.jpeg#1456x0,s7WL8RRJ-6KZKHk9dU1Ck7K5OhSeveGeEWKYMCFROHwU
This apparently comes from https://github.com/willnorris/imageproxy/blob/572ad2db78ed5ad6b892cedb92899ef412144409/imageproxy.go#L304
Any ideas where this comes from?
