I am experiencing problems when trying to install apps on devices with iPadOS 26. It works fine on 18.6 and older. The error I am getting is "A TLS error caused the secure connection to fail." It works fine on mobile hotspot, so it has something to do with our corporate network and the changes that Apple made with iPadOS 26.

Is anyone else experiencing these problems as well?

Are you using 802.1x or WPA2/3 password related wifi?  If the former, are you using user based auth or certificate based auth?

 


We are using the former with user based auth.


New enrollment or an upgraded device?  Have you attempted to forget WiFi and then readd WiFi to accept the certificate trust again?
