The HMRC closed my portal due to physhing concerns, we have now set up a new portal which works, and QB is activated for VAT transactions. However my PAYE FPS submissions are failing, I know the gateway credentials are correct. HMRC say they can't see any failed submissions, although I've tried more than a dozen times. Where is it going wrong? I've ticked "Save Gateway credentials" in QB but it still asks for the password every time. I've renewed the credentials in the MTD configuration section, and cycled the HMRC connection, still no joy.
