Hello, ppq.apple.com appears to be unavailable. The issue is reproducible from multiple networks/devices. Requests to https://ppq.apple.com fail, preventing iOS from verifying developer-signed applications. This results in the device displaying an error indicating that an Internet connection is required to verify the developer/app. The issue appears to be server-side rather than related to the developer certificate or provisioning profile.
