I have a site that works without problem on Windows, Android, and Mac. For reference: https://xamina.co.kr

I first suspected it might be a problem with my AWS certificate and maybe the ipad does not recognize Amazon's trusted authorities so I tried updating my ios. My ipad's certificate version is now on 2018.12 but is still causing the same problem. My customers are begging for ios support and I can't seem to find a solution.
