Failed to retrieve configuration on iPadOS v15.8.4

[dletkeman]

Heads up to my fellow Jamf community.

We've been seeing iPadOS 15.8.4 iPads when reprovisioned can't be enrolled to Jamf School.  This may affect Jamf Pro too.  The exact error is "Failed to retrieve configuration".  I reached out to Jamf support and they said they have been getting reports of this from others and that this has been observed across different MDM providers.  Jamf reached out to Apple regarding this issue and this is exactly what they told me:

Apple did get back to us just a bit ago, and they have identified the issue (they did not elaborate on what the issue was). The release is not ready yet though and at this time they couldn't give me an ETA on when that would release.

For now I created an internal Jamf Product Issue so we can track customers and I have attached this case to that ticket (PI136109).

Hopefully an update that fixes this issue will come out soon.  Jamf did say that they could reproduce my issue but had mixed results as one test iPad had the issue but another one did not.

On another somewhat related note we have also seen iOS 12.5.7 devices not being able to be reprovisioned either.  Error on that is somewhat different.  It says "The configuration is not available.".  I'm not pursuing this as iOS 12.5.7 devices are not currently supported by Jamf School.  We were using these devices as communication devices for our special needs students.

Thanks for the information. Luckily we have very few iPads with an iOS below 16.x and most of those are being retired. I will have less than 10 that are being used for ELL and kiosks, but the likelihood of them needing reprovisioned is minimal. But just in case I'm making a note of this.

Has anyone who contacted Apple heard any more information from them? We maintain about 40 or so older devices that are below iOS 16.x, and, thankfully, only 2 have been affected as they were wiped for reassignment. It doesn't seem to affect currently enrolled devices.

I had Jamf contact Apple as this deals more directly with MDM than a personal product and we don't have Enterprise support with Apple.  Jamf said that not all devices were affected and that Apple has identified the issue so there is hope that this might be resolved.  Most likely we will have to wait for an iPadOS update to fix it though as this just effects v15.8.4 devices.

Hello.  We are having this same issue.  We are able to get the devices into JAMF by enrolling via URL, but the internet won't be filtered offsite.  Has anyone found a way to enroll the v15.8.4 devices with a configuration profile into JAMF Pro?

I've been using Apple Configurator 2 for these older iOS devices. Once they are enrolled that way, they all are supervised and seem to have all the assigned profiles working. FYI, we are using Jamf School.

Jamf Support said they have mixed results regarding this.  They can reproduce the issue but not consistently.  So beware.  Some may not be able to be reprovisioned.  So far we've had 4 I can't redeploy.  Jamf Support said it's something Apple has to fix on their end and will likely need an iPadOS firmware update.

The process can be a pain in the neck as if I don't do the steps in the exact right order, it will give me an error message that the device needs to be enrolled using DEP.
