I’ve started to have this issue since I’ve started using CloudFlare a few days ago.
curl -I https://islamcdn.com/quran/public/fonts/uthman_tn09.otf shows that the access origin header is coming through. However, when I browse to https://alquran.cloud, I’m still getting the error in the browser.
I had this at the last cdn provider too and they made a change at their end to fix this. The header is coming through, so can anyone help identify what I need to debug or ask CloudFlare to debug?
