"Your account cannot be created at this time" on a brand new device.
I purchased an apple TV box for my uncle. He has never had an apple product before, but he wanted a channel they have. When trying to make him an apple id to get that channel, it keeps saying "Your request could not be completed at this time. Your account cannot be created at this time." We waited and tried again. We tried on his smart phone. We tried on my Samsung. We tried on my iPad through safari. Nothing works. Everything is new and never used to create accounts before, none of the other troubleshooting I've read about applies to or works with this situation.
