Yes, many people are having this problem; and judging by the fact that your device is brand new, it's not an issue with our devices having been unlocked before. It is probably an issue with the unlock server again like it was back in 2012.
See this thread on XDA-Developers: https://www.xda-developers.com/asus-unlocker-tool-broken-asus-claims-rma-is-the-answer/
Hopefully, whoever controls it can fix this issue again.

Hi elias888
Thank you for your asking. Based on your device is brand new, like AgentTechnoman said, your issue should be different from theirs.
Yet because your model is ZB631KL, please refer to the link below as Max Pro Series, and open a new thread there

Please provide me the screenshot of your error message and your issue in your new thread. Then check on your inbox and PM me your SN. I will forward the information to the relevant department.
