Register iPad Air 2 in Apple Business Manager with Apple Configurator

I initially tried to connect the iPad with the MacBook and execute the process. The iPad was reseted but not registered in the Apple Business Manager. After this failed, I tried to scan the blue circle on the iPad in the network area using my phone. However, no blue circle appears. What can I do?

Every device is on the newest software update.

Now I got the Error: Provisional Enrollment failed.

Provisional Enrollment failed. [MCCloudConfigErrorDomain – 0x80EF (33007)]
