I'm trying to host my profile/cover pics on my site, which is hosted on cloudflare pages, but somehow those pics won't load in iOS clients and some web clients (only nostrgram works).

Nostgram loads the url directly and puts it in css background url, snort tries to load the pics through some proxy. I edited _headers in cloudflare, but I'm probably missing something else. Any ideas?

This is in my _headers file in cloudflare:

/*

Access-Control-Allow-Origin: *
