This error is returned from HMRC - this usally happens if the VAT number is incorrect or if you have not yet registered for MTD. If you have registered then you need to make sure you have received the confirmation email.
The best thing to do is to log in to HMRC directly and check that MTD has been enabled, I would also double check the VAT number is entered correctly.
