Let me help you get past this problem and ensure you can seamlessly integrate your Amazon Business account into QuickBooks Online (QBO), Cvoisey.

To start with, I recommend contacting your bank to check if there are any issues that may be causing the connection failure with QBO.

Also, could you please let me know if you encountered any specific error message during the process? Knowing this information will help me provide a more tailored solution.

In the meantime, you can clear your browser's cache to remove excessive data build-up that impacts the platform's performance. After doing so, attempt to re-link Amazon for Business to QBO.

If the issue persists, consider using other supported browsers.

Feel free to add a reply if you have additional questions.
