https://ppq.apple.com throwing certificate error

A few of our enterprise app users started reporting that they could not launch our apps and were seeing an error prompt "Unable to Verify App".

They have an active internet connection.


Trying to access the url in a browser shows following "Your connection is not private" error

NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED

We are also seeing this with a number of our enterprise apps that are being deployed via our MDM. However, we are not seeing this issue on all devices the apps are assigned to, just a small handful.


We've seen that wiping the devices and then reinstalling the apps gets them to install successfully, but this is a very painful and time-intensive solution.


Please reply if you figure out the root cause of this issue.
