Question: Question: Profile Installation Failed - The SCEP server returned an invalid responseHi all, I need a little help please. I had devices enrolled on profile manager with a profile installed. However I did a dumb move and deleted the profiles manually via settings. Once the profiles where removed I then tried to apply the same profile via our MDM server thinking I didn't have to remove the devices in the profile manager first. Now after the blueprint and profiles are loaded onto the devices via the MDM, I try to enroll them and get "Profile Installation Failed - The SCEP server returned an invalid response". I know this has something to do with not removing the devices via profile manager first. I think the profile manager still thinks the devices are managed. Just wondering if there's a work around for this so I can get the devices managed again. Hope this made sense 🙂 Thanks in advance for you time and help!
