Hello,
I’ve been using CF image resizing for over a year on an IP restricted dev site (using .htaccess IP protection, not a CF WAF rule).
This did work fine up until a few days ago but resized images don’t now display (the original displays fine) and I get the following error code via the CF image resizing page:
Origin returned 4xx HTTP status code
If I remove IP restriction, the resized images display fine again.
I have tried allowing all the CF ip addresses but to no avail.
I’m struggling to understand why this would suddenly stop working?
