There was an ANZ outage that happened due to a recent change on the ANZ website which interrupted the QuickBooks bank connection.
As a result of this change, if customers are signed into ANZ internet banking website and simultaneously attempting to connect with ANZ account in QuickBooks, customers will be prompted in-product to sign out of other device e.g. ANZ internet banking website (error 179).
This is a result of a ANZ security setting limiting the access to ANZ on multiple devices/browsers. Please sign out of any other instances before attempting to update your bank feeds.
If this persists then please get in touch with our support team who will help you troubleshoot or escalate this further if needed.
