Mac Enrollment Timeout

Existing devices in JAMF (e.g.: reenroll)?  Or are these brand new devices without a JAMF record?

If the former, purge the old record and try it again. 

The devices were enrolled previously. However I already tried deleting the old records before reenrolling. Without success.

What macOS version are these computers running? Jamf Pro may not allow you to enroll computers with unsupported operating systems?

See the release notes for supported versions.

I tried it with macOS 15 and 26. Both had the same error.

​@Andixon have you deleted the partitions or volume and created a new one? I can’t explain why this would have an affect but starting from scratch with a fresh OS may work. 

Since only a few specific MacBooks are affected while others enroll fine, this is likely a device-specific state issue.

Recommended fix: Boot into Recovery Mode → Erase the drive → Reinstall macOS.

Already tried both. I always erase the drive as completely as possible.

Tried different internet connections?  What’s the system clock showing on the system?  Were these turned off/shelved for a long period of time?

Different internet connections make no difference.

The time that is showing it not correct. But that should not be the issue. The time is never correct at this point. It sets itself to the correct time after the enrollment. 
No, the one I am testing with was enrolled just before.

The clock’s time may actually be very important. Most modern systems require clocks be within a range of about plus/minus five minutes from the current local time. This is a security feature to thwart using old certificates that may have been revoked or expired.

If a Unix-based computer sits for so long that its battery depletes, the internal clock will reset to January 1, 1970 (Unix epoch time). A manual time sync is often the only way to restart time sync when it’s that far off.

Thanks Bill.  See, I know what I’m talking about sometimes.  And yea, the enrollment cert has to be within a valid window for it to actually enroll and not timeout.
