Thank you for bringing this issue to our attention, Dan. I understand the importance of resolving this matter promptly so you can keep track of your banking data. Let me share some solutions to address this issue.

To begin with, I suggest checking your bank's website to spot any potential announcements, messages, notifications, or alerts that could be causing this issue. If you come across any requirements that need action, address them immediately.

If everything looks good, return to QuickBooks and link your account again. If the issue persists, you may contact support to investigate this further. However, if you receive a specific error message, I recommend following the solutions from this article to fix it: Fix bank errors in QuickBooks Online.

Once you have successfully connected your bank, the system will automatically download your bank entries. All you need to do is to review and categorise them to the appropriate accounts. 

Please let me know in the comment section below if you have follow-up questions while connecting your bank account to our system. I'm just a few clicks away to help you again. Have a good one!
