Hi joupin-hotmail-c,
Welcome to Community! Getting an error when accessing your bank feed in QuickBooks Online, can have a negative impact on your day. I would be glad to assist!
I recommend clearing cache if you haven't done so already, as the browser may have an excessive amount of frequently accessed page resources, which can cause some errors and/or unexpected behavior. I also suggest opening your QuickBooks Online account using another browser such as, Firefox, Edge, Google Chrome, Safari, or a private window.
If you experience the same result, please don't hesitate to contact us outside of Community. It would provide a great opportunity for us to work with you on a personal level and review the issue in more depth, so it can be escalated for further investigation if necessary.
If you have any other questions or concerns, feel free to reach back out. We would be happy to help!
