Nationwide had an unexplained 24 hour outage.
Nationwide's API was returing 405 and 406 errors. This is teh first time the 406 error has occurred with regards to Money Dashboard. We think that this may be as a result of changes to the credit card connection. The fix for that was scheduled for the credit card issue we submitted last week (Ticket 12126)
This issue has been resolved.
We have lots of nationwide customers who are once again reporting errors with transactions and refreshing. This effects the credit card and current account customers so we have no idea what is going on. Nationwide replied quickly once we emailed them, but the error was still out there for 24 hours.
