Not sure if this is a HAP issue more of an iPad one but someone may know something to help.

I have a RapidSSL certificate assigned to my server which plays well but when I browse to it via an iPad it comes up with

This website requires a certificate

When I click continue it asks me to so select a certificate and lists 2 with identical numbers. No amount of clicking helps.

I have tried to install a Root CA but it doesn't help. There's lots of stuff online that's similar but nothing helps, talks about deleting a keychain but have no idea as I am a newbie at iPads.

Anyone got an idea?
