I keep getting an error message that says something unexpected has occurred when I try to reauthorise my HSBC business account - how can I solve this?

Having this error when reauthorising your HSBC account in QuickBooks Online may occur when there is ongoing maintenance on your bank's end. You can check your bank account directly to see if there are any notifications about scheduled maintenance.

If there are none, try using a private or incognito browser to reauthorise the account. If the issue persists, you can also try using another supported browser.
