Activating CDN( on The DNS Page) issues with Safari / iOS


here is a weird thing
everytime i activate CDN on the DNS page all mac safari ( only ) browers and any iOS browers ( chrome, safari…etc ) doesnt load at all… when i turn the CDN off it works perfectly
I am on ubuntu 16.04 ( apache + nginx ) / wordpress website
My subscribtion is the 20$ per month…
so i am really at a lost here


But it works with other browsers?


yeah every browser ( accept safari on mac ) and all broswers on ios devices ( iphone / ipad)
it works on
chrome / firefox mac
all browers on pc
andriod phones
