iOS won't trust private CA certificates

Hello,


I have a certificate chain like so:

Root CA -> Intermediate CA -> Server Certificate


I install the Root CA and Intermediate CA certificate on Apple devices via a Profile created in AC2. I install the profile on my iPhone and trust the Root CA (as iOS still doesn't support trusting Intermediate CAs), and try and visit the server and it tells me that the certificate is not trusted, the iPhone recognises it's signed by the intermediate CA but does not give me much more than that.


I also installed the certificate on my Mac (just trusting the Intermediate CA this time), and it works in Safari, so I know the certificate is valid & the server is working.

iPhone 14 Pro Max, iOS 17
