The bank has not cancelled the authorisation.  Quickbooks will not connect.

I hjave cleared caches, tried private browser windows.

I have tried Internet explorer, Microsoft edge, Chrome, Opera and firefox.  What browser would you recommend I try ?

I have tried desktop, mobile and laptop.  Broadband, mobile and wifi.

TSB still has valid authorisations.  This has not expired. Quickbooks has decided not to connect.
