HMRC comments are:
We have observed a steadily increasing number of 404 ‘Not Found’ responses as sign ups to MTD increase. Our investigation has established, the majority of these responses are being returned correctly and it is normally where a user is calling for pre MTD information.
MTD APIs only call data relating to MTD, the user’s historical information will remain visible via the legacy channel (by using your government gateway login).
Therefore, when completing the request to fetch for VAT periods we recommend ensuring that the Open (Outstanding VAT Returns) radio button is selected instead of Open and Fulfilled (Outstanding and Submitted VAT Returns).
If the error occurs with this option selected, the only other issue is that a restriction implemented from HMRCs server could have been met. This would be an intermittent issue which should be corrected when you try again after approx. 10 minutes.
