Claude was connected and working but now I'm getting an error stating the app you’ve selected isn’t available for use in your country (I'm in the UK) Suggestions to fix?

I had Claude working with QBO but now when it attempts to connect I get this "error" message "Unfortunately, the app you’ve selected isn’t available for use in your country. Try contacting the app publisher for more information, or select a different app to use in QuickBooks. We’re sorry for the inconvenience." However, I'm in the UK and it was working fine. Something maybe worth noting when I go to the Help, it goes to US not UK (don't know if that has anything to do with it).
