Cannot Enroll Gen 5 iPad using Apple Configurator

Using Configurator 2.18 for Mac on a Macbook Pro (macos sequoia 15.6).

Seems to be not able to add ipads running 12.5.7 ios. only up until recently though. Gen 8 and above all ok therefore know is not a network issue or anything like that

Connect iPad via USB (ipad as mentioned is an iPad Air 12.5.7). Wipe or restore to factory with Configurator.

Once done, select and Prepare.

Manual Configuration, tick add to ASM, add to my server etc..next next next

Click Prepare. Get this result everytime on the

"The cloud configuration server could not be verified. [MCCloudConfigErrorDomain - 0x80EF (33007)]

Anyone know if Apple Configurator now cannot enroll older ipads?

thanks
