Problem creating new Apple ID. Account cannot be created at this time
I like to check Apple system status when I can’t use their online services.

It has a contact link for when you have an issue that isn’t described. As mentioned in the comments - it’s not easy to know if you need to retry or there’s a more permanent issue, but waiting is always an option to avoid a call to support. I would try once in a few hours, then again tomorrow, then ask support if you haven’t waited a little to try again already.
