User Profile

I'm using JamfPro Cloud to try out the new Enrollment Flow "Account Driven User Enrollment". I have one domain exsample.com. After authenticating that domain with ABM, I created one user. Then I built apache as a web server for that domain. I set it to be accessible via https and set the JamfPro cloud Enroll URI with ".well-known/com.apple.remotemanagement" as JSON. Then I tried signing in with an exsample.com ABM user from settings> general> VPN and Device Management on my iPhone, and when I ran the apachetop command on the target server and confirmed the request to ".well-known/com. apple.remotemaagement". But then I get the following error: "Your Apple ID does not hae proper privillages to perfom this action" Does this Enrollment Flow assume that the MDM server is on-premise? What's missing in our settings?
