Help setting up new iPad Pro

Try as I might, my new iPad Pro won’t cooperate with me, and I keep getting an “error connecting to iCloud” message when I try setting it up from my latest iCloud Backup. Even if I try to set it up as a New iPad, it doesn’t work.

I've tried the following to fix it:

-Checked on Apple’s side, to see if there are any issues. None at all.

-Made sure my date and time were correct.

-Logged out and back in of iCloud, via iTunes/App store.

-Power on/off. Multiple times.

-Tried sending a verification code from my iPhone, which is logged into my iCloud. No luck.

Please help!
