I recently added Cloudflare CDN to my website. It works really well on all devices except iOS 11 on some ISP IPs.
Most of my users live in Iran and they use ParsOnline, SabaNet an Shatel DSL.
they can access website with
x.x.x.x ip on windows and android
but they can’t access with
x.x.x.x ip on iOS 11
with VPN they can access my website even on iOS 11.
this is my website Url: https://z4car.com
I’ve tested other websites with cloudflare and they didn’t work on iOS 11 too.
