Hi,
we are providing a MDM solution and the servers use self-signed certificates. Till iOS 15 we were able to include the CA and host cert in the .mobileconfig for MDM and the checkin-url certificate was accepted.
Since iOS 15 when installing the .mobileconfig profile, the checkin-url certificate is untrusted. We fulfill all certificate requirements. I also tried pinning the certificate for checkin-url, but that also results in
Domain : NSURLErrorDomain Code : -1200
Did anything change in iOS15 that I oversee? Or is it broken and will be fixed in the next release?
Also, importing both certificates to the phone and trusting the CA in settings does not work.
TIA Tim
